First, I tried to install Season One on this computer (Vista). It didn't work. I got the securRom patch, but that didn't help. (Except now I get the mouse icon turned into a cd-rom icon before the game crashes - yeehaw).
Then I downloaded Season Two (or the first part of it, 201). Well, it won't work either.
I've tried updating DirectX. I've tried restarting my computer. I've tried to run the game as administrator. What else can I do?
