I've been using PBP 3.0 gold, MPASMX and MCSP for the last few months without any problems. I decided to update MPLAB to version 4.1 and I loaded XC8 C compiler. Now when I try to compile something...

Good luck getting any sort of help. MElabs and Mecanique seem to be too busy with other projects to support their legacy products. I recently purchased PBP Pro 3.0 and MCSP full version and am...
The program was under development and being debugged when this problem cropped up. The "end" was part of the search for the cause of the chips becoming non-programmable.
