Sorry to tell you this is a scam .. No money goes to Limewire, and You do not really know what you are getting, it may be filled with adware etc..
Limewire basic is available free from
www.limewire.com ONLY as is Limewire Pro which costs US$18.88 for 6 months of free updates and email support.
Contact the scammers or your CC company and get this payment stopped as you have been a victim of fraud.
Two sticky threads at the top of many of the forums will give you an idea of the problem. Optain p2p programmes only at official sites and Musicmembers get you $$$$$$$ back
