I click the trainer, 3 second pause, Windows Problem Reporting shows up, I choose "Close program", trainer process stays for a while in the Task Manager.
That something is really getting on my nerves. I will explore a little, to see if anything can be changed or done.
But if I don't find anything would you recommend changing my OS from W7 to XP, as a last resort of course? I don't think that any Windows XP users might have had this problem so it might be safe to assume that whatever program it is, it's somewhat usual for W7.
Seconded. Open task manager and go to processes. End the ones running under your username one by one (Except for explorer) until the trainer works. If that doesn't do it, then I'm stumped.
Don't close anything running under Local Service, Network Service, or System.
