Oh no!
That means you didn't get an email from the official LimeWire Pro people, but from one of the scam sites that are pretty good at making people *think* they are getting Pro.
You might be able to get your money back: see the stories of how at the long thread here

Can you post the email you received (just snip the personal info) so others can be warned?
Thanks
