So I'm sure you've heard the song before, but after trying to sync my notes with Ubuntu One(on 10.10 AMD64) I get "Could not synchronize notes. Check the details below and try again." Of course the problem is that there are no details and trying again doesn't help. So I ran tomboy -debug and compared my error to any thing I could find about similar problems (such as the post here) but found nothing useful.

Any way here's my first error, I got this using preferences>synchronization>Ubuntu_one

The next thing I tried was using preferences>synchronization>tomboy_web with the default 'http://one.ubuntu.com/notes/' and got the same error plus one more.

I Have also tried removing then re-adding My computer from my Ubuntu One account, but that did not help either. The only other Thing I have noticed is that under system>preferences>ubuntu one >services, "Notes" is not listed as a service. I don't know if this is normal or not. Thanks for any help and please let me know if anything is confusing.
