I to have found some problems with the way PSDSoft compiles the ABLE files. My problem was with paging, if I used the page register as a word, the result for flash sector 0 was wrong, all others where OK. If i explicitly defined the sate of each bit, then all was well. I'm currently running 5.21 I tried 5.26 but it would not programm my parts at all & crashed my system. I've downloaded 6.02, but I'm afraid to install it ;)

this is what I had to do . . .
fs0 = ((address >= ^h8000) & (address <= ^hBFFF) & !pgr0 & !pgr1 & !pgr2);

Best of luck.
