Thank you for your reply.I apreciate your thougths about it.

It worked on the acts1-2, but not anymore. <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />
It's not working with 1,45 neither, I just installed.I don't have any video filters, my pc was fresh formatted, no programs installed, except BD and directx 9.I played a lot of games on this computer, didn't had but very rare minor prbls untill now.I owned a pc shop(I made my own computer) and I know some things about computers, but this one is above me.
Should I install windows XP? I am willing to do almost anything.

Dd made me buy a new computer, because the one I had was a little slow.You can imagine how much I liked it.Don't think I will do it again with Bd though.I am not sorry about the money spent on the game, I just really like your games and want to continue play this one.
