The official site offers Pro ($21.95, free updates & email support for 6 months), Extended Pro ($34.95, free updates & email support for 12 months) & sometimes a one-off deal where you can buy Pro for $13.95 but don't get any email support or free updates... if you paid $ 49.90 then you may have been scammed.
The only official site for download of Pro or basic (free) LW is
Lime Wire ยป Download LimeWire
On your CC statement, the vendor should appear as LimeWire LLC.
Membership? - **WARNING ** BEWARE** - Download p2p Clients ONLY Thru Official Sites
If you did get scammed, you should contact your CC company & see if they can cancel the charges.
Do you mean that when you try to download a file, you get a popup from LW saying that LW can't find a license for the file? In that case, check out this thread:

Or do you mean that you can download files, but when you go to play them you get sent to a website?
Or are you trying to play files with Windows Media Player & that's giving you the error??
