I've had Lime Ware for a while, but I have a question -- and it's a stupid one.

I want to get rid of my old computer, but that's where I have my Lime Ware account loaded right now. When I originally got it, I paid for the lifetime usage and therefore, don't get a monthly bill. Now that I have a new computer and want to download LimeWare there, how can I access the account I originally set up?
