Binary package hint: ubuntuone-client

i've been working with ubuntu one in ubuntu 9.10 version. I update to 10.04 and ubuntu one still running right. But I downgraded the version back to 9.10. and ubuntuone-client doesn't work. The icon in the icon tray appears with a red signal and when I click over the icon appears the APPort bug comunication:

I'm sorry to hear Ubuntu One isn't working properly for you. Can you try the following and let me know the results?
1. Quit the Ubuntu One client. From the applet select Quit. Then open a Terminal (Applications > Accessories > Terminal) and run the following to quit the syncdaemon.

u1sdtool -q

2. Delete the old metadata. In a Terminal run.

rm -rf ~/.local/share/ubuntuone

3. Start Ubuntu One as you normally would Applications > Internet > Ubuntu One

You should be connected after you follow these steps. If you are not connected, can you please attach your Ubuntu One logs to this bug report? Please zip your $HOME/.cache/ubuntuone/log/ folder and attach the zip here.?

Thanks in advance!
