Happens everytime I want to execute a command (ie. attempting to load up a WoW instance.). Changed nothing to the settings whatsoever prior to getting this error. Although I had an ugly systemcrash that caused me to reset my PC, as soon as I wanted to execute a command after start up since, I'm getting this error. What must I do to continue to satisfy my WoW addiction now!

I've never had an error of this kind and have no idea whatsoever on how to counter it. I would prefer not reinstalling my PC or anything drastic if possible, so trying my luck here first. :P
