You may have to try a different injector for your 64 bit OS, but you said this still happens without hacks? I have had a weird problem like that since I been using Win7, if I move my mouse or click anywhere while the warrock login screen is loading it will crash back to desktop. Other than all that make sure your GFX drivers etc. are up to date..
