Sean, I was able to load the file in warp13 without a problem. I don't know why you're getting the page fault. Since the file loads at this end it probably doesn't matter that you're using a newer version of MPLAB.

The problem is that when I try to open the HEX file (generated by the latest MPLAB, v7.2) in the Warp 13 software, it gives the following error: WARP13 caused an invalid page fault in module KRNL386.EXE at 0001:00002268.
