First two things that come to mind:
- C-BOT (the compiler) has a 64 byte limitation on file names. Your path is quite large, try moving all the files into something smaller (I have C:\FIRST\Code)
- Make sure that all the project paths are set correctly. I'm not too sure how to do this without having MPLab in front of me, but I'm sure if you search around you'll find an explanation.
