For those of you with issues, please pay attention:
64 bit Mega Xp crashes the game, but the 32 bit version works fine, so use it.
Both trainers work fine, with the one issue I just listed.
Follow the instructions on HOW TO USE the trainer and you shouldn't have any problems.
Maybe click a few...
CAN CONFIRM 32 BIT WORKS FINE, 64 BIT STILL CRASHES ON MEGA XP.
You have to run the game first, get on your character and walk around for a second or two.
Pause the game.
Alt tab and find the trainer file.
Right click, open as administrator.
Use the hotkeys and it works fine.
