800x600 is the only setting for my desktop

I addressed that earlier in this thread.

Try this.  Open up a terminal (Menu->Accessories->Terminal).  Copy and paste in the following two lines, one at a time.

Code:

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

Then try opening Lite Software (Menu->System->Lite Software).

If the above doesn't work, then try the following.
1) Reboot.  (Menu->All->Turn Off Computer) and then select Restart.
2) After rebooting and you're back at your desktop, make sure no other window is opened and run Install Updates (Menu->Favorites->Install Updates).
3) When updates are done, close any windows associated with installing the updates.
4) Then try opening Lite Software (Menu->System->Lite Software).
