Problem occurs, when i load from the beginning and go through the portal to third area. i change to the real form and run up to stairs, but right after that, game crushes. anyone have the same problem?

I have the same problem, the game keeps crashing when I try to go into the "Melchiah zone" after loading a savegame. I was able to go into this area without problems during a first play, but now it crashes at a very specific point ( Taking the portal > Going into real form > Opening a door > Going a bit forward > Crash ), maybe when the game tries to load the new area.

I had the problem earlier in the game, for me something must have corrupted in my save. I was only able to get past it by using a different save file from a bit earlier. Haven't have an issue since then.

HOpefully you've been making multiple saves. Try an earlier one.

i didnt, but im at the beginning (not even hour of playtime) so it won't be problem to start again and having on my mind to save on diferrent saveslots. thanx :)

Same problem here. Third zone, a little advanced to the point of having 2 big square boxes one on top of the other to reach a new zone above, past a small kind-of-lake, open a door, go up, and almost to reach to the part with a big platform with an small elevator in one side, the game crashes.

Tried multiple times, same part everytime... :(

UPDATE:
I decided to try for a last time, but this time I decided to walk this part in spectral form... and it worked! :P
I don't know how or why, but it worked. Now I was able to finish that area (the platform, burning some pillars) and to face the first boss: Melcaiah.

I had the same kind of bug on the CD version (in two different places). Having multiple saves helps indeed (or even making a backup regularly).

Good to know that going to spectral may help though!
