In my opinion forget about using PM, always use MPASM. Later PM will nor work when you get into different things.

Now I forgot to tell you when you set the fuses in code space you will have to comment out some lines in the chips *.inc file that is in the PBP directory.

Or you can modify the *.inc file.

My inc for this chip looks like this.
Code:
