Sounds like you did. Where did you buy LW from?
LW basic is free & Pro costs $18.88 USD for 6 months of updates & email support. The only official site for either download is www.limewire.com

If you've been scammed, contact your CC company & report it. Ask them to cancel the transaction. They may or may not advise you to cancel the card, just keep an eye on your statements to see that no more payments are deducted!
