If you get Pro from www.limewire.com then it's not a scam.
Pro connects you to 5 ultrapeers, compared to basic's 3, which gives you better search results. You can download from 10 hosts, compared to basic's 8, which gives you a faster download speed... when you're downloading from the maximum hosts.

You're really only going to see the benefits of faster speed if you had a reasonable speed to begin with. If you're on a very slow speed then it's not going to make much difference.

There's a no refund policy for Pro, because the basic version is offered for free.

Have a read through this thread, it's got lots of advice & tips for getting the best performance from LW
