Flex/Air Update Object Issue...

Question

The following code is from the Air Employee Directory example
to which I have added an Update Object, the app installs and
updates with no problem, but as soon as the update is done and it's
time for the app to start, the app just doesn't come up. It was
working fine before I added the update object... Any idea on what I
could be doing wrong?
