Which site are you going to when you try to buy LW Pro?? The only official site is Lime Wire » Official Website & Free Download, BitTorrent « & there's no 'lifetime membership'

Pro costs $24.95 for 6 months of free updates & email support or $34.95 for a year's worth.

360Share is a scam...you should contact your bank/CC company. Depending how long ago you paid, you might still be able to get your money back.
Membership? - **BEWARE** - Download p2p Clients ONLY Thru Official Sites (click on link)

get your $$$ BACK!!! (music members)

Good luck
