If you paid $30 for a years subscription, I regret you were scammed by a site which was not Limewire. This is happening all the time I'm afraid!
The Basic version of Limewire is free, and the pro version costs 18.88$US this gives better connection and six monthes of on line technical support and pro updates.
see:
http://www.limewire.com/english/content/download.shtml
I advise you to down load the basic ... check all is working fine and then update to pro when you wish.
Before you install the new limewire, just check that you do not have any prefence folders for the old limewire on your computer. You could search the computer and the file or folder would be called .limewire I think if you use Windows. Any old preferences should in your case be deleted.
Normally Deleting the old preferences is not neccesary, but in this case it migt be wise.
