Q:

Application launcher is missing

I have 13.04 installed from a DVD that I got on eBay but the application launcher is missing. I've tried CCSM but it won't work!

A:

If you can't download the CD, you could buy from the Canonical Shop here: http://shop.canonical.com/product_info.php?products_id=976 
We don't offer support to variations of Ubuntu, forks, unofficial variants and derivatives are not controlled or guided by Canonical Ltd. (list on Wikipedia) and generally have different goals in mind. You should ALWAYS download/buy Ubuntu from trusted sources, preferable directly from the makers. You should verify your CD, so it won't include defects or modifications.

Insert your Ubuntu CD into the drive of the computer that you want
to run/install Ubuntu onto.
Turn the computer on, or restart the computer.
While booting from the CD, hold any key to access the CD menu. 
At the CD menu, choose 'Check CD for Defects' (if you never get to
the menu, try BootFromCD)

You can also order CD's from a third party at http://www.osdisc.com/cgi-bin/view.cgi/products/linux/ubuntu
