Lost Limewire Pro

I actually paid money for a better version of this program. It was all well until I got a weird error. After the error I had to delete my Pro (after I emailed my issue to the Limewire support) thinking that I would be able to get the program again. Now a long time and two homes later, I have forgotten the email address that I used to get my Pro. Is there anything that anyone can tell me that will allowi me to get the Limewire Pro I paid money for.
