Welcome to Ask Ubuntu! As it stands, your question may need a little more information in order for it to be answered. If you are not technically savvy don't worry, just add as much information as you can, can you provide a screenshot so that you can get an answer (and a good one at that). – Mark Rooney Mar 25 '12 at 7:55
