Not sure why you think getting scammed is funny with your lol's? Make sure that transaction IS off your bank/cc card ASAP and report it as fraud. Paypal, from what I know doesn't do refunds & neither will clickbank, it's like pulling teeth. Never be so willing to giveout your cc info online unless its an official site.
www.limewire.com IS the only site to get Limewire.
good luck.
