I needed to uninstall, and reinstall U1, in windows 7, then I have to wait on the "getting info, please wait" screen, after this, when I want to log in, then it says, "authentication failure". Then I tried to reset my passworld, and then it tells me, I'm not even registered. From the web interface, I can log in. Anyone has ever experienced this problem?
If you installed the 3.0 Windows update we are rolling back the update due to a bug. We are recommending all users so back to using 2.0.3 until bug is fixed. We have been seeing a lot of authentication issue.
Here are the steps:
Uninstall Ubuntu One
Restart your computer
Download http://one.ubuntu.com/windows/ubuntuone-2.0.3-windows-installer.exe and install it and let us know if that worked for you or not
