I have Windows 7, all previous Trainers worked, not sure what you mean by saying to buy a new Computer?! I have been a member since many years and I never inspected such an answer, not customer friently.
So how in the hell could we make a trainer for the x64 version of the game if the game has no x64 client? You people on some kind of medication?
I have been doing some testing and found out that the armor and health stat really effects my computers ability to load the battles. I tweaked the armor down to 200 and health down to 50 it loaded much faster. It also got rid of the ridiculously long health bars above the characters head. Once I reduced the armor and health down to 20 (Which is still plenty to keep everyone alive) everything is loading much quicker.
