Pickit 3 programming problem

All of a sudden, I have a problem programming a 18F1220 w/ pickit 3. I'm using MPLAB v.8.56 and ICSP. It has been working well with same chip, same board and same program header.

Now I get a message in PK3 output

See next post

I must have pushed wrong button!!!!!!

Anyway, the message is
The following memory regions failed to program correctly
Program memory address:0000 0000 Expected value:0000 0006
Received value: 0000 0000
Programming failed

I think I remember getting this message a while ago but don't remember how it was fixed. I tried programing a different chip and it worked fine. What could be the problem? Thanks Aaron

Hi Aaron. Why did you start the other thread? Anyway, you can find plenty of answers on your second one, here.

I hope you figure it out soon!

Best wishes,

I believe they are 2 separate problems and didn't want to group them
