Purchased Limewire Pro but email addy not recognized
 

I purchased Limewire Pro just a little while back and then bought a new computer. When I tried to install Limewire Pro my email addy was not recognized. I don't have the original email, but I do have a bank statement showing I paid the upgrade amount. I couldn't find a number to call for support, so I'm not sure what to do. Please help!

Thanks
