I had to do this to, although i already had done it some time ago, something strange happened to my MSE. It turned itself off and gave me some strange message that freaked me out so i ran all checks i could and found a trojan.
That resulted in me formatting my PC, which i should have done anyway some time ago. Anyway, i tried your suggestion after i still had the same problem with the trainers.
* Updated game trainers and cheats daily
* Get notified when new cheats are added
* Request which games get new trainers
* Priority support with any problem
