In addition to needing f/w ver. 3.0 (as I've seen many have already responded), I believe you also need MPLAB 5.62+. Look at the readme files for MPLAB and PICSTART Plus. 18F compatibility should be in the list of revisions. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
