After completing first mission (tutorial) you got credits? NO MORE! Just put that folder to the game folder

You should have now 3 folders in your game folder (Dlc, Local, Packs)
It work for me, does it work for you?
Dear GOG, if this work can you upload this as official patch?

They can just made .exe file who will install that 2KB of data do game folder. :)
Have you tested my "patch" Omerta works good?

Has anyone tried this guy's fix yet?

Worked for me.

Work? That's great! :D Now I can send my CV to Kalypso! xD
Now it's the time for Georgia Avenue and that bugged 3 objectives... But it's not for my nerves. :/ Somebody can fix this?

That has been fixed by someone else: http://www.gog.com/forum/omerta_city_of_gangsters/patch_107_and_work_for_gog_version

Reupload of my patch: http://catshare.net/OUr2siYwbdkB44Ny/Dlc.zip

Can you repost a new link for the homemade patch you have? Seems I cannot get either link to work.

Either that, or perhaps some description of how to fix the issue.... create empty folders?

Thanks Cz

I cant' reupload this files because every patch that I upload will be deleted by gog Staff, also I don't play this buggy game anymore so I don't have this files.
The best way to fix this crash is... Download pirated version from warez site, full version with that new DLC "japanese something".
In this version you will find folder called "Dlc", you can put this folder to GOG version and then you can pass first mission... Or just play this game from warez with japan DLC.
I know this isn't good solution, but this game isn't worth any moneys, because this game is unfinished.

I save this, it should be less economically incorrect.
