Ubuntu One has worked fine for me for several weeks and I now have 8.2 GB of files in the clouds. Then, last night, Ubuntu One stopped working. When I fire up
System > Preferences > Ubuntu One, it tells me that I have 8.2 GB stored (13.2 %) and that my status is Unknown.
I've tried to restart to no avail. I even tried to remove, followed by clearing the password keyring and starting over. Still nothing. I've run out of buttons to push.
