The Universal Programming Module is basically a 40-pin ZIF socket on a small board with an RJ11 socket (? ICD2 connector) and a patch-setup so that the pins of the ICD2 socket can be connected to any of the 40 ZIF positions, as needed. So the user "wires" the socket as needed for any particular chip - hence the "Universal" description :-) I note the OP didn't mention connecting PGD and PGC, so this may be his problem!
