Just to throw out there, it might also be the app BEFORE ToDo Matrix that it is halting on, preventing TDM from being backed up.
You may be able to tell by the timestamps (by sorting the directory), and possibly look at the newest timestamped app.
I don't know much about ToDo Matrix, but if it's anything like AlertMatrix and some of the other Rex apps, you should be able to just download the app OTA, and then log in and your information will come down from the servers, no?
