ubuntuone will not sync folders other then Ubuntu One

Back from holiday and I got a really annoying problem. On return, I updated 12.04 that I have dual-booting with 12.10 testing. I also installed a video driver that was offered - and wrecked the whole thing! After re-booting, I got a failure and dropped to the command prompt. startx failed as it couldn't find a valid screen (whatever that means). I gave up trying to mend it and re-installed then re-updated. Now, I had no problem with Ubuntu-one under 12.04 before, and have no problem on my netbook - also on 12.04. Setting up Ubuntu-one went as normal and synced the Ubuntu-one folder, but offers me no other folders to sync from the cloud. I can't find any way of making it work. Putting up a fresh folder on my netbook immediately shows a popup on my desktop telling me that the new folder is available for sync - but it dowsn't show in the Ubuntu-one window!

The I had to re-install 12.10 for a fairly similar reason has to do with a newer AMD accelerated graphics driver. I'm now getting exactly the same problem with Ubuntu-one. Anyone got any ideas?

I have put screenshot here:

The one on my new installation both Precise and Quantal.

Here is the one from my netbook (working OK) with Precise:
