I subscribed to Limewire PRO several years ago. When I upgraded to Mac OS 10.4 I found that my old version of Limewire required system 9 and I didn't want to download the old system. When I tried to log onto the forum, it asked me for my email address. I entered it, but the system told me that there was no record of that email address. Why not?

I still have a receipt for my $18.88 payment and the reference number associated with that account.

How can I get the OS 10 compatible version of Limewire and how much will it cost me?
