I am not familiar with PiKdev but the values of "FFFF" in the Program 
Memory field strongly suggest that the hex file has NOT been loaded 
into PiKdev's memory.  Try to load the hex file manually - use 
PiKdev's "load" or "import" function to actually select your hex file 
and load it into memory.

You should see data other than "FFFF" in the program memory locations.

The un-programmed state of a PIC is in fact "FFFF" so it is quite 
possible that PiKdev is programming and verifying the PIC correctly.
