I supposed to it won't be a problem for options but when i star trainer and press F1 and other option keys, trainer stoped working without any caution. I also tried both ways: Start trainer first and game than and start game first and trainer than but nothing changed. I deleted trainer and reloaded it again and it didn't work. I hope you could help me or give me some advice. Because i really love this game and i need this trainer.
I'm sorry for my bad English, again.
EDIT: Uhm. I think promlem is about CH servers? Because my other trainers aren't working too.
It's because your anti-virus.I have the same problem with the Call of Duty 4 trainer,but I just stopped the anti-virus program,and it work. Try this,if it can't help,and I can't help you anymore.And I sorry for my bad Eanglish(I am from Bulgaria )
