hello, I'm having problems..ti seems every now and then my s2 just locks back up and I'm a demo racer again, this is all well and good if I have an unlock left, but if you don't, it means no racing that week. I currently run vista home premium on a 2,4 ghz duo core, 2 gig ram. Also when I try to upgrade from x to the new x, dunno the patch name, it says it's unable to upgrade..
HELP!
