for me Master Reset and Master Clear fixed this problem.
Was getting "Over the Air" Sync error message from Motorola phone tools (couldn't sync at all) and didn't find the answer to my problem searching the forum, but did find a link to the phone tools forum where I found this thread:

In order to fix the problem I had to uninstall and than reinstall with out letting the software update to the newest version. Thought this might help some ppl.
