Microchip used to have a file on their web site that fixed the problem. One of t
he new PC's at work would not talk to a Picstart Plus (firmware 1.20) when MPLAB
3.40 was installed. Reverting back to 3.31 and using the replacement MPPLUS.DLL
allowed me to program chips.

MPLAB 3.31 is still available from Microchip. I couldn't find the DLL fix for 3.
31 at their web site when I needed it last. Copied it from a PC at home.
