I've even tried cut and pasting the ASM code from the data sheet, but to no avail.
Sounds bad to me, sounds like you have a corrupted INC file OR there's something bad in the PBP-Plugin installation or in the project building process.

can you post all your files generated in MPLAB (MCW and all other in a zip) and or a COPY/PASTE of the error you got.
