Same problem. I suspect it might be win8, since it played fine on win7 x64 yesterday, but today, after upgrading, it crashes upon launch, no matter the compatibility or admin options. Oddly, the Metro 2033 trainer works fine. oO
I have already sent my request to update the v1.3 of the trainer. It does crash instantly on Windows 8 even with IE10 disabled. Offline key doesn't work either. Trainer claims to be compatible with Windows 8 but is not.
