Can't add anything useful about the Pic in question, but I just went
through a painful Pickit3 adventure....

Bought six new Pickit 3, couldn't get a single one to communicate with my
development machine (win7-64, MpLab 8.87, selected device dsPic33fj128mc804=
)
Plug one in, Mplab hangs on connecting. Unplug/replug it connects, but
hangs on downloading bootloader. An older (six months?) Pickit 3 works fine
on this PC.
After many hours of frustration and hair pulling, I did a virgin install of
MpLab 8.91 on a different computer. Plug in the Pickit3 and it connects and
updates all the relevant firmware - now they work fine on my development
machine too.
