Regarding the Mega Trainer 1.6.0.2, Super Health, Unlimited Stamina, Re....

Originally I was having an issue with the trainer. Hitting F1 would not enable it from within the game, and had no effect outside of the game. I read somewhere else that issues arise in trainers as sometimes S:COP launches two instances of the file "xrengine.exe.". Here's what to do:
1) Launch the game
2) Alt-tab out and launch the task manager
3) Kill whichever process is using less memory (for me it was using less than 1mb). This has no apparent effect on the game.
4) Launch trainer, rejoice.

thanks a lot. this really helped. I was almost ready to give up on it

This worked for me as well. Thanks!
