Well basicly i have done the quest where Dragon Rider attacked the other Marked One...ok so we teleported and woops...black dungeon...then i see sucubus and a blue cage...strange problem ><
here are some screenshots
please help me ><

It looks like something bugged out and your either under or outside of the normal map area, do you have a earlier save you can load before that happened?

Take a look at this post. . . =)
Edit: I would make another save (different name) with the corruption and repair it rather than your only save at this point.

well i don't think that replacing a file will do the work because when i talked the last time with Zandalor (before sucubus part) it was loading...loaded just a little bit and then started a new load (wtf)...well im just gonna try the world file part and write the result...
btw Rallack it happened before too...for example i tried to go to Verdistis and i was just like magic teleported to the orc camp...(and teared into pieces)with the "double" loading of course
hm...my file (world.x0) is 9,788...i think it isn't the problem..should i try to paste another file (world.x0)into this one?
btw...i forgot to write about another bug...they maybe are connected...well,when for example in Iona's Dungeon i've done the lower lvls and got back up and found that strange sword...i was "teleported" to my windows O_o

I would make a save under a different save name, shut DD down, try the repair on the new save, open DD and load the repaired save. If it doesn't work for you, just delete the extra save from the load menu. Otherwise . . .
What OS are your running, is it 64 or 32 bit? What video card? What CPU, is it dual core? If running Win 7 or Vista . . . did you install as an administrator? On the game shortcut, did you right click it, click Properties on the resulting dialog, click the Compatibility tab and check mark "Run this program as an administrator' ? Did you try running in other compatibility modes?
Edit: Also, look on the bottom right corner of the start menu and confirm you are running game version 1.005A

oh God im not an computer expert xD
well the version is 1.0029A
well my computer : Intel (R) Core (TM)2 Duo CPU
E7500 @ 2.93GHz
well system : Microsoft Windows XP
i can't save in the "space" where the Zandalor is trapped

This is probably why you are having problems, assuming you are running a game you purchased from GOG.
You need to make a backup of your save directory, which may not work any differently since they are corrupted. Go to the the game in your GOG account and download the patched version (1.005A, it's the only version you can download).
Uninstall Divine Divinity, delete any DD folders left under Program Files\GOG.com\Divine Divinity and install using the newly patched version you just downloaded. Move your old saves into the new install. The corruption may produce the same results in the new version but . . it won't happen again, you will probably need to start a new game . Give that a try . . . =)
Edit: I played all the way through on the unpatched version . . . it was VERY difficult with all the bugs . . . =)

gonna try the patch now...if it works you have my love forever lol
well i patched it and installed the crack (i've lost the disk)and doesn't work..probably wrong patch..

Well, I am not condoning or encouraging the use of fixed exes. Use your best judgment on the legalities of it . . . I am assuming you have purchased the game legally rather than insinuating you are pirating.
You would, however, need a fixed exe for the patch number you have installed. If your fixed exe is for the older patch (1.0029A) . . . it would not work with the newer patch . . . you would need to locate, download and use a fixed exe for V1.0034A.(V1.34) You would also probably need to install the patch with the original game exe in place. Since you don't have the original disk . . . I believe you are going to find the game is unplayable with or without a patch / fixed exe.
Again, your best solution is to purchase the GOG release . . . so . . . for $6 you are legal, running the latest patch, have a copy that is XP / Vista compatible and have access to support for the game . . . =)

wow...stuff i love you lol it works ^^

Glad to hear you have it working. You may still have some problems running the older version especially on Vista.
I also suggest that you don't use quick-save (CTRL + S) when you are playing. I found that it sometimes corrupted my saves, not sure why. Using the S key alone, I have not had any save corruptions. This may not be a problem in V1.005A but it was in V1.0034A.

Stuff...can you help me again?it's kind of the same bug (not sure why)
i've found that 7 guys and activated that gong...watched the scene and sudennly i was again in the black dungeon (dead)...i couldn't see my character...my health bar was 0.. and some of the controls don't work (for example i can't make a screenshot),and i should be in that desert ><

It sounds like you have a combination of a bad fixed exe and a game version (any ver prior to 1.005A) that was nearly unplayable on XP / Vista. The original release on GOG was almost unplayable as well. That's why I kept suggesting that you buy the GOG release. Larian Studios took several months to produce the V1.005A patch which fixed the game for XP and Vista. This was most unusual for a publisher especially since the game was seven years old. I still suggest you purchase the GOG release to play the game with minimal problems.
As far as the problem, no fixes come to mind. I have not heard of the problem you are experiencing with the transition from the ceremony to the wastelands before now. It could be a fault in the fixed exe or the retail version not working with your OS. I'm sorry that I can't give you a fix but I have experienced nothing similar in my game play.
Like you I am a gamer and I am in no way affiliated with GOG so . . my recommendation to buy the GOG release is simply to point you to the best release for the game. I feel your pain but I have no idea what you could do to fix the problem . . . sorry . . . =(
