Trouble Programming EEPROM

Hi All;
I'm not sure what's going on here; I write my program an run it fine on my PDB and on my Prop Demo Board as well as on a Prop Proto Board. These last two are of the "Prop Clip" variety. So now I want to store the program in EEPROM on the boards, and that will only work on the PDB. On both, the Demo Board and the Proto Board, things seem to proceed properly for a second or two with the activity indicators showing "Loading", "Programming", "verifying" etc., and then an error message pops up "EEPROM programming error on COM 9".
What might be amiss here??
Cheers,

Unfortunately following the debug suggestion of reducing the latency from 16 to 1 millisec did not change anything. I still can write and operate code via the RAM side, but cannot get it to program the EEPROM.
I have plenty of proper power to the boards.
Any other suggestions anyone??
