3.Delete them all and restart the Ubuntu One icon.

and now it works for me.

I think it must be some error breaked during the sync and can't resume .
hanging dead. what I do maybe make it a restart.
Just used this resolution for Windows 7 Pro x86 with version 3.0.0 of Ubuntu One client for Windows and worked great! Thanks!
