Ubuntu One :: Client Won't Start And Now Music Downloads Aren't Working?

I had the "set-cap" exception problem, so when the fix was released, I updated. Since then, the ubuntuone-preferences dialog will not start or work. I tried the me bar, the system menu, and the CLI.Now, I bought some music the first day the store opened and it downloaded fine. Then yesterday I bought another album and the store hangs on "downloading the files." Six hours later, it still won't move.

It gets weirder. The music store says its trying to download a couple of tracks from the first album (even though they are already downloaded), the second album shows up as downloaded under the Web UI, but doesn't show up at all on my desktop .ubuntuone folder.I've tried the IRC a couple of times, with no response. (In fairness, it may have been bad timing, I'm in New York) I don't mind trying to sort this out myself, but I'd just like some more hints. I've looked at the syncd log and found the exception, but I don't know how else to restart the syncd. At the same time, my files *are* synching, and *one* of my address books is synching (my gmail account contacts aren't). I know this is alot at once, but I'm afraid of dividing the problem and missing something.
