Feedback, Complaints or Problems

I have not been able to get a few of the trainers from this site to work. Any help in solving this would be great. Three games come to mind, The Witcher enh.ed, Crysis, and Dragon Age Origins UE all on Steam. Witcher for example will load but after game starts I press F1 but this will crash the game, saying "The Witcher has stopped working, A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available.". Has this happened to anyone else? Any ideas on how to fix this from happening?
Thanks

Right ok. Check to see if you have E10 on your computer if so Revert it back to IE9. As IE10 seems to interfere with the older trainers.

Thank you for the response. I have tried to run The Witcher again after using this method to uninstall IE10 support.microsoft.com/kb/2821327 but no luck, the game crashed and had the same message.

IE10 would only cause problems during the authentication. Your problem sounds more likely your AV is blocking the trainer or any other securit software does. Disable them all, run trainer as admin and try again.

Ie10 interfere with the trainer authentication not with the activation as far as I know, anyway check if the trainer and game version match, disable all av/firewall, run the trainer as admin...

Thank you for the responses. I have tried both of your guys suggestions but to no avail. I have tried both AV and Firewall, also tried running in admin. Tried all three in a various number of ways, but no luck. Trainer is the newest one available and the game is up to date according to Steam.
Any other ideas?

See this KB article on restarting your PC in a state known as "Clean Boot Mode" which enforces starting your PC with only services and programs that came with Microsoft Windows temporarily which can help eliminate if the issue is a third party program interfering:
