Lots of things suddenly stopped working...

Hi all

I'd really appreciate some help, as I'm at a complete loss to know what to do. About an hour's searching on here has not found an answer.

Suddenly, the following have stopped working:
* Connection Management - window opens and connections are editable, but clicking on 'connect' does nothing - for either wireless or Ethernet (and yes, I've switched the switch on the front
* My Documents, My Music, My Pictures, My videos, My Downloads - click does nothing.
* My Files - Shows 'My Disk' but nothing else. Clicking 'My Disk' does nothing.
* My Files - as above, USB memory stick is not detected.
* KPowersave Information - claims the AAO is plugged in, when it isn't.
* Terminal - Can't type in terminal window - so no hope of running diagnostics.

My OS is Linpus Linux Lite v1.0.6.E
BIOS version is v0.3109

Any help would be appreciated. Is it a complete loss?

Thanks a lot
Ade
