All you have to do is: like you did: call your cc card or bank, depending what kind of card you have and cancel out that transaction. You will most likely have to fillout fraud papers etc. Just alert them that you've been scammed/conned online. If they are decent and dont give you any grief, they should be able to cancel that out without a problem and it should show on your next card statement. DO NOT PAY for it! If you pay for that transaction, you WILL not be able to get your money back.
www. limewire.com is the only site to get Limewire from. The free google ads on top of this forum, is rather stupid because those are not limewire sites either.
anyway, you might also have to change your cc number becuase the scammers will use it. if you see any other funny charges on your card cancel that number ASAP!!! keep after your cc billing. Because sometimes, they dont do what they say they're gonna do for you.
Never be so willing to give out your credit card details online! Make sure that when you get your statement that transaction was cancelled from your bill.
also, I wouldnt use any fake version you bought. Id get rid of it and get the real limewire basic, it's free. gnutella is a free, open P2P network, you dont have to pay for any P2P app to connect to download from other users.
