Do you know why that would happen? Outside of restarting, it isn't giving me any problems, I can play it all I want without a single error. But apparently no one else can open it...
Maybe I'll just send a bug report and see if they can't figure it out. If not, then... I dunno, copy and paste as much as I can to a new cap and see if that fixes it?
EDIT: Turns out the file's too big... grahhh. Guess it's the latter option, unless anyone has a better idea.
