Sadly you seem to be the latest of many to be scammed. If you go to
www.limewire .com you will find two forms of Limewire.
Basic is free Pro is $18.88 with six months support and updates.
Try to stop your payment then, with apologies to ultracross but I'm too lazy and tired:
Get LimeWire ONLY from the Official Site:
WWW.LIMEWIRE.COM (Click Here)
LimeWire Basic is FREE! If you downloaded or purchased LimeWire from another source besides the official site, please see THIS! (Click Here)
