Chip connection failed

I just soldered some headers on my SX52 proto board, checked for solder bridges, found none. When I try to RUN my LED prog to check whether the pins are live, first test, I get "Chip connection failed", close that error window and the next window shows that the "Download was successfull", but the program does not work as expected, nothing happens.
Does anybody know what causes a chip connection failure. Yes, I double checked to make sure that the SX-key was firmly seated.
Any ideas.
Thanks

Make sure the MCLR pin is NOT held low.
Can you program a new SX protoboard ?
Just soldering header pins by itself should not make the SX not program.

I have three more SX52 proto boards left, I checked them out, and they program without any problem. I used the same power supply just to make sure the conditions were the same. The board that is giving me the problem is right out of the anti-static bag, it's brand new. Unfortunately, I did not test the board before I soldered it, I made an assumption that it was just fine. This makes two boards in a row that have now died with some kind of problem, the first one lasted about a month before it died, some kind of Vpp error comes up, and now this one. Either I am having some very bad luck, or ...
When I mentioned headers, that includes four apiece on the Vss, Vdd, and Vin. I will stop here, otherwise I will start sounding like a whiner.

They don't take kindly to high voltages like that.
