I think the trainer is simply perfect at this point, thank you very very much Cal =)
I have the same exact issue that you have. i have gone though and made sure firewall is not an issue, and i do indeed have 64 bit OS and for some reason everytime CH gives a trainer for a 64 bit game and its a 64 bit trainer i cant do it and no solution can ever be found why.
I bought unlimited a long time ago. with this bug i run into it sucks......but most times its not an issue, i have ran into it twice. i in this case go to another site and grab a diffrent trainer cause i cant use this great awesome one. so i have to settle for a far lesser trainer when it comes to 64 bit only on this 64 bit game with my 64bit OS lol
