1. When i start the game, a warning appears which says in translation: "Failure when moving a file or folder: File can't be moved: Source not available."
I can click "OK" and the game starts after a long while.
The game is installed on a different disk partition than the running operating system.

2. I got stuttering sound issues while playing the movies.

3. I get an Error message everytime the game tries to autosave, autosave is not possible (can't write to disk or something like that), i have to save manually which wouldn't be much of a problem, but that error message is very annoying.

4. Graphical glitches which seem to be a problem of having an ATI graphic card. Some people in Steam forums tried a different atioglxx.dll to fix the glitches but if i put such a DLL in the folder, the game doesn't start at all. Are there any other workarounds?

I have to say, i'm somewhat disappointed by GOG not mentioning known problems of a game in the game description, so that one can read about it BEFORE buying the game. I bought lots of games here already, but every 4th or so doesn't work cause of "known" problems or issues. If it's just a game for 2,99$ i won't mind, but for games with a price of 9.99$, i feel somehow cheated.
