Your computer is broke--BUT, I'm willing to take it off of your hands
. All you have to do is ship it to me. Heck, I'll even be nice enough to pay for the shipping.
Seriously, you might just want to try a reinstall (I know, this takes up time and isn't very fun). Clean all SH3 "stuff" off of your drive, defrag, and try again. It could just be a corrupt file. Also, if you're using SH3 commander, make sure that you've installed the GWX files that you need to properly run the program with GWX.
Good luck. Software problems, and all computer problems for that matter, drain my life force from me
