I think i have good news for some people that can't use the trainer. I couldn't get it to work until. I turned 'User access control' off. You can get to it from user account in control panel.
User Access control huh?
Hmm I'm not a huge tech guy but I assume you're using vista yeah?
XP and SP3 ftw then heh
Just like to say that I had zero problems with the Add Experience and Unlimited Ability Points options. I think you just have to turn them off after you use them. Also, certain abilities are tied to certain wargear, so it's possible that wargear might have become unequipped and that causes the loss of abilities.
How do you get the unlimited ability points? Also which key for the unlimited ability points? cheers.
