OK So far I've done the following;
Turned off Deep Guard, Turned off F-Secure. I even uninstalled F-Secure. Still No difference.
I then tried to "run as administrator" (I cracked the pass word I had thanks to Schrullenhafts suggestion of a cool program) unfortunately I still get the same error message.
Should I try to re-install the game now that I don't have a anti-virus installed?
Any suggestions would be much appreciated.
