Hello, this error is just baffling me because I've played Silver Chaos (with the English patch) on my Vista already and had absolutely no problems with it. I tried another run through with the game to get a different ending and it gave me the error "MainSystem.exe has stopped working."
I tried re-installing it the exact same way I installed it before and then I got this error twice in a row. http://i26.tinypic.com/dpjq6p.jpg
Followed by this error message http://i31.tinypic.com/2s6o8qw.jpg
Then when I try to play, I get the "MainSystem.exe has stopped working" again. I don't know why it is doing this since it worked just fine before.
