Gnutella Forums - Can't upgrade my LW Pro... PLEASE HELP...

OK... BIG problem.
I bought my version of Limewire Pro a LONG time ago, and I've had a few different e-mail addresses since that time. Most of these e-mail addresses, I cannot remember.
That was my first error, but here comes the doozy that relates to my problem here...
The most I EVER did, concerning my Limewire Pro, was to buy it. I never partook in any forums, creating an account or anything of the sort. I also never knew that I could update the version of it that I have (I'm not used to that, since every other program I've ever bought requires me to rebuy the new program when there are updates/new versions to it). I'm just NOW learning that I can finally update what I've got.
Here's where the full dilemma' kicks in...
I went onto the website, and tried to download these updates. It asked me what e-mail address I had at the time that I purchased it and I completely froze up.:shoot: I put in every e-mail address that I COULD remember, but it was a 'no go.'
I just upgraded my entire computer, because my old one completely fried (hey, sue me... I continued using Win98SE until this new computer, which is the newest anybody could get), installed my version of Limewire Pro into it... and it keeps giving me error messages.
OBVIOUSLY, I need to upgrade it. And OBVIOUSLY, I'm a dillweed for not catching up to everything a LOT sooner, I know... thank you for thinking/stating the obvious.
I thought there was some kinda' contact info to get ahold of Limewire here, but that's also a 'no go' (unless of course you can also verify that same e-mail address that I have no clue of and no files pertaining to it, thanks to a new computer, because of the old one crashing).
Would it be possible for somebody to either get ahold of Limewire for me, and pointing out that if they can read this, they'll know my dilemma (in my own words)... or somebody here get ahold of me, if you know for sure everything of what I need to do in order to fix this situation? I'd GREATLY appreciate it.
My current (and probably permanent) e-mail address is details removed and my name is obviously Jim.
Just in case you're wonderin', the version of Limewire Pro I have is 4.10.0.1... I know... ancient, in today's standards.
I appreciate all of your help.
Jim
