First things first -- I am a complete GE/MA-Com NOOOBIE; this is my very first commercial radio that doesn't have the batwings on it. So go easy on me

Now to my problem. My setup consists of the following:
- 800 M-RK with the DTMF keypad (is this aka MRK Scan?),
- ProGrammer EDACS4 software,
- an older version (or clone?) of the P96A RIB, and
- the PriceIndustries MRK-1 (non-ribless) programming cable.
Turning the radio on with the cable attached, radio displays "PC PROG". So far so good.
Click Read icon in ProGrammer, a prompt asks New Radio Type, I choose "MRK Scan"
Now reading process starts. I see status updates proceeding in the software (reads RAM, ADI file, etc) and I see both red LEDs flickering on the RIB. After about 10 seconds, I get the following error in the software "Could not initialize radio", and on the radio, I see "PC PROG" on the top line and "APP ERR" on the bottom line.
Any advice on what the problem is and how to fix it?
Oh, one more tidbit I forgot to mention: without PC cable attached, radio displays "PERSDATA" and "ERR=0500" on the display. Guy I bought this from said that is because the radio has no personalities currently programmed in it.
Hmmmm, did I just answer my own question? Maybe there's nothing to read? Ok IF that is the problem, then am I correct in creating a new personality for "MRK Scan" or should it be "MRK II"?
