Hmm, maybe your compiler doesn't have support for that particular instance. I Remember how conio.h didn't exist in the SciTE compiler I used, as I'd have to use conio_mingw.h instead. It was strange.

Tinker around with things though. Download multiple compilers and try them. Or do like WetWired said, comment out the line.
