If you paid for LW Pro, then you will still have the email they sent you with the link to your personal download page (if you purchased pro less than 6 months ago.) That is of course if it was Lime Wire LLC you actually paid. If it was any other company then unfortunately you must have accidentally gone to a scam site pretending to be LW. There's lots of them around; Known Scam Sites (click on link)

No the gnutella network is free to use.

Not sure what you mean you uninstalled Gnutella. Perhaps the LW program, but saying you uninstalled gnutella is like saying you uninstalled a satellite if you connect via satellite connection. Must be a big computer to fit all of gnutella users inside. lol Sorry silly jokes.

If you deleted any email with LW, then access via this page Lime Wire » Support

As for connection problems. Best I can suggest with details at hand is try these tips: If LW Will Not Connect (click on the blue link)

(BTW I moved your thread out of the Phex program section & over to the LW vista section.)
