IDE stuck at "compiling Sketch".. (SOLVED)

Hi,

Yesterday my code was working fine but today, my code will not compile. It will just stay at the Compiling Sketch part for hours.

I tried commenting the entire code off and leaving just the setup and loop functions and it still won't work.

Any ideas?

Also, its my first library so I think its probably some kind of library error. Ive tried compiling other code and it works.

Post your code, we're not mind readers.
Probably a typo somewhere involving ; ) or }

I got it. It turned out that I put

#if (ARDUINO >= 100)
#include <Arduino.h>
#else
#include <WProgram.h>
#endif

in my .CPP file instead of the .h file.
