I have 36 trainers and 6 do not work. They crash right after loading with the message [NAME] Trainer Has Stopped Working. They no not even make it to the authentication. The trainers are:
CitiesXL 2011, Hydrophobia, Moutn & Blade Warband, Serious SAm HD, Torchlight, Tron: Evolution.
I have disabled the firewall and all anti-virus programs with the same result. I am running IE 10, but the other 30 trainers run with no problems.
One of the work arounds for the authentication issue, is to download the offline key.
