Thank you for the links, but they do not help me. Maybe I didn't explain myself clearly. I only use the simulator to write the code which I burn into the chip which works 100% in my real life circuit. I use the melabs U2 programmer. Regarding reading the datasheet, I have it and I always refer to it when working on my chip.

I am trying to NOT use the simulator program anymore so I can only use PBP. But it is not working.
