I'm sorry to hear Ubuntu One is not working properly for you. If you would like to help debug the problem that would be greatly appreciated. You can do the following in order to provide important details that will help determine the root cause of this issue.

1) Quit the Ubuntu One client. Open Applications->Accessories->Terminal, then run the command:

2) Run the following in the Terminal:
mv ~/.cache/ubuntuone/log ~/.cache/ubuntuone/log_old && mkdir ~/.cache/ubuntuone/log

gedit ~/.config/ubuntuone/syncdaemon.conf

#Add the following two (2) lines to this file and save:

4) Run the following in the Terminal to start the ubuntu one deamon/service:
u1sdtool -c

5) Let Ubuntu One run for a while, copy some files into your Ubuntu One Folder.
