completely uninstall all AV, firewall and other security software. right click run as admin on trainer. run trainer. run game. alt tab to trainer and press f1 to activate. alt tab to game and use options.
I didn't have to uninstall AV software, but I did do the ALT-TAB thing and it worked. never had to do that before, but as long as it works.
The trainer only works on single player mode? Also, is this game worth $70.00 U.S??
Yes. Unless you want to risk a lifetime EA Ban and they are good at detecting the cheats as they run "Fair Play" detection on their systems as well as player reporting.
You only want the cheats for the hard more single player missions for the credits / badges. Everything else is in multiplayer.

yep single player only. not worth the price tag, but there are some sales going on at the moment so you may be able to pick it up cheap. its just light on, there aren't that many maps per mode, no server browser, and a clunky multiplayer game finder. its still fun, but don't expect to be playing this for years. 3-6months tops, unless they add a heap of new content.
