I've soldered PGC/PGD right at the 16F628A in-circuit with the same 0000 error.

I'm also using an external power supply for the circuit, the same supply I used when this was on breadboard.

I don't think this is a configuration problem either 'cause I made sure to breadboard this circuit beforehand. This was the 1st time I upgraded a 16F628 to a 16F628A and I wanted to be sure of the configuration settings.

Frustrating, and I'm sure it's not hard to fix this either...
