Anyway, after trying everything I cold think of to fix the problem (to no avail), I finally just said 'fuck it' and re-installed Di's OS. Since this is Windows, I'm not sure why I didn't just do that in the first place...guess I was not quite awake and thought I could fix it. Heh, what was I thinking?
Anyway, works fine now, even repaired a nagging little problem from previous. Still haven't gotten any food, though...
