Well I've been waiting quite a while, and it still says, Compiler: Default Compiler and Status: Rebuilding... No errors and no warnings.
Is it supposed to take a really long time?
EDIT: Got it working now. Unfortunately, there are now 17 more errors... Why would somebody release such a flawed program!? T_T
Or maybe instead it's written in C rather than C++... Sigh... So confusing.
