ok i might be able to get ure chams to work. this is for corndogs chams
1) Disable UAC on vista
2) As soon as your computer starts up disable your anti virus. This has to be done immediatley. I know this sounds crazy but this is how it works.
3) Start up perX and load the dll's into it.
4) You have to do all this as soon as your computer starts up
5) Then start combat arms, if it crashes reset your computer and repeat the steps.
6) That is how i get them to work on my computer
I got no idea why all this has to be done so quickly but it actually works and i figured this out.
