Your problem is that you only downloaded MPLAB and not C18 as well. MPLAB is the freeware microchip IDE. By itself MPLAB does not support programming in C, only assembly. You need to download C18 which is a C compiler pluggin. Follow Max's link to get a 60-day trial of C18.

BTW i would try to stick to C18 and not the Hi-tech compiler. Each has slight deviations from ANSI standard C that may get you into trouble. There is a possibility that the default code will not even compile with the HI-Tech compiler. It also uses a different project file format etc. You *may* also run into a problem with the fact that there is a .o file included w/the default code and i doubt that the .o format is consistent btw the compilers.
