When I press F1 in game with trainer 16 I get an annoying repetitive activated response (ack,ack,ack,ack,ack) that does not go away and none of the trainer keys work. The only way to stop it is to shut down the trainer. I have run the trainer in both admin and non-admin mode. Purchased the game from Steam. Shows as version 1.260. Using Win 7 64bit home edition. Is there something I am missing?
