If you bought basic LW then you were scammed. Basic is free. Pro costs US$18.88 for 6 months of email support & updates.
The only place to get the official, clean versions of LW is www.limewire.com

If I've misread your post & you do have a legitimate version of Pro (under 6 months old) then there are links here to help
