Since i am aware that some external programs may cause problems with games, please let us know
what version of Windows you are running (like, 98 , ME, 2000, XP and also if it is russian or english)
what translators you have installed (sometimes they cause problems, so let us know which ones are installed and running)
what other programs are installed (you can see the list of programs in "control panel" in "add / remove programs"
Try to run this program "end it all"
before you start the game. Information on "End it All"
This program will close all programs running, including the ones you dont see. Test if this solves the problem.
I am not in anyway related to or employed by Larian, but for them to find the problem, they need to know EXACTLY what programs you have, what windows, what language programs, etc.
