I don't know whether installing either software will help. Do you know, or can you tell, which version you have? You said you didn't change it, so I am guessing Dingo, but that is not guaranteed. If you have Badger you might try upgrading to Dingo. Other than that, I would think you would be better off getting unstuck before attempting any changes.
Did running the battery down do anything for you?
Anybody else have any suggestions??
