Can't open crossfire hacks at all or OMFG injector

I can't open GHook_CF. I installed the windows Visual C++ thing, and when i run GHook_CF it comes up with an error message: Windows cannont access the specified device, path, or file. You may not have the approriate permissions to access the item.
And Cheetah injector won't inject, and OMFGZ injector says the same message.
I've disabled AVG and Spybots TeaTimer thing. I am currently running on administrator on Windows XP.

What am I doing wrong :S?

lol dont run on administrator if ur on windows xp
lol... try to turn off your user account control.. will work 97%

didn't work, im using windows XP, no user account control :P

and im not running it as administrator, i meant i have an administrator account
