I had a similar issue. All I did was grab a Steam install and install over it. Seemed to work fine.
Finally got it sorted, after many many attempts lol.
I took both HDD's out and connected one to my brother in laws computer by usb, formated and installed XP then upgraded to 7 again and voila
EDIT: Stopped working yet again, getting very frustrating now.. It worked fine, i installed all my usual programs, restarted PC everything was great.
I come back to it an hour later and turn on the PC and it gives me the same error
I have officially gave up nothing I do will work ?
Thanks for the reply, although I tried that also
I carried out a complete format of my hard drive, installed windows, then installed steam and it worked until i restarted my pc.
The problems have only started since the last title update, so does anyone know when the next one is due possibly?
EDIT: Finally fixed it now, I have to disable my internet connection and start it up for it to work n then just enable and sign it
Thanks to everyone for the suggestions and help
