Oh o
Other people have had a similar problem, but it turned out that they were scammed into thinking they were getting Pro by lookalike sites.
see
http://www.gnutellaforums.com/showth...threadid=28751 for some stories of how some got their money back
If the real LimeWire support site here
http://sales.limewire.com/support/? doesn't recognize your email address, chances are you were scammed, because you are well within the six month limit.
hope all works out for you.
