18F4550 programming failed using PICkit4 while verifying "User ID memory"

[Demon]

Any idea what it's crying about?



I had to slow the programming speed to SLOW or else I'd get speeding errors.

Program, configuration and EEdata memory seem to verify just fine. It looks like it failed at "User ID memory" - whatever that is.

This was programmed 15 years ago; no idea what's on that memory location.
