There is a controller fault, producible with bad software, where the controller won't run and the program state light is on, while it really is not in program state. If leaves you stuck because it indicates program state but won't load a new program. The controller will come up in this same state every time you power it up, so power cycling it does not clear the problem.

In this case, hold the program button down the right number of seconds to put it in program state, it was 3-4 seconds as I recall, but don't expect any light changes to indicate anything. Then load a program that is known to be good and this should get you going. You can then re-try loading the possibly errant program and learn that it is in fact the errant program that is causing the problem.
