Does this happen even if you haven't opened it before (e.g. after you restart)? Or is it just a matter of the game not closing properly after you've opened it once?

If this is the only game having this problem, it might also be useful to contact the developers' support directly or ask in the MW2 forum here.

Я решил проблему!
Путь к игре должен быть исключительно на английском языке.
P.S. I solved the problem!
The way the game should be in English only.
