Thanks Bruce and Robert. Since I posted the original post I have purchased the full MCSP package but I have not tried the ICD method again. I had assumed that what Bruce said was the correct method and no bootloader was required.

My original problem was that it worked fine on a sample program that I believe I got off the Rentron site. So I know the basic hardware was good. When I tried it on an actual project it would hang up after the first few executable lines - and not always in the same place. I don't remember what the project was now but I think the problems came during the initialization portion.

All my 'stuff' is at my office and when I get a chance I'll try the ICD again with the new MCSP.

Thanks again, Mark
