Just to follow up on this side-thread...

I am able to problem a V2 board with a PICkit 2 programmer. I doesn't work
from the USB port on the front of my Mac Pro, but it does work from the Mac
Pro when plugged into a powered USB hub or directly from my MacBook Air.

I use a PICKIT2 and have had no issues programming the V2 board. Maybe you
have a faulty unit, or your USB port can't supply the required power.
