I agree. I guess I will have to break down and buy a new receiver.
What do you all recommend?

Everything seems to indicate that you are not sending any DiSEqC commands. You could try a known good DiSEqC switch and test it on a known good port to a known good lnb with a known good signal. That would prove/disprove that the command protocols are able to be generated and can be carried to the destination thru the cabling and connectors.
Another thing to try is to do a factory reset or even re-flash back to factory fresh FW, to be certain that the DiSEqC subroutine FW on the box hasnt been corrupted. I would back up your channel/sat config first via Channelmaster so you dont have to redo all of that again. (While you are there you might want to add the CW feeds on 91W if you do C band.)
Let us know how you made out.
