Hi Al,
 
Did you try both controllers?  If it got corrupted, hopefully it wouldn't be both controllers at the same time.  I'm pretty sure you can't view the map for the B controller with the EM2, but looking at the A map will certainly tell you something, particularly if you have any notes about how it was set before.
