Okay, done some testing:
Configurations:
1) Win XP, Ati Radeon X1600X, Intel Core2Duo, 2 Gigs of RAM, retail version, no noCD
2) Vista 32, GeForce 8800 Ultra XT, Intel Core2Quad, 2 Gigs of RAM, RLD release, noCD
3) Vista 32, GeForce 7800GS, Athlon 64, 2 Gigs of RAM, retail version, noCD
1) trainer crashes after about 5-10 minutes in skirmish or single player
2) trainer crashes after about 5-10 minutes in skirmish, single player runs fine until you encounter enemy
3) trainer crashes after about 5 minutes in skirmish and single player once you encounter enemy or have built a hero
Sorry, Cal, but the trainer seems non-working
