Moving LimeWire to a new computer

[umpiredice]

I have a truly ancient computer - a P2-350 with 128MB RAM and two hard drives, 6.4GB and 120GB (guess which one I installed myself). Although the old beast has performed faithfully over the years and still does ALMOST everything I ask of it, it really is getting long in the tooth. Sooner or later, I'm going to bite the bullet and get a new computer.

Can I simply copy the LimeWire installer I downloaded last year, from my old computer to my new computer, and run it again? Or am I going to run into registration problems ("You are attempting to pirate an already installed version of this program! Prepare to be shot!")? I have LimeWire Pro 4.8.1, so my subscription for free updates has probably run out. I'd rather not have to fork over the money again, so if anyone can tell me I can just re-run the old installer on the new computer, I'd be most pleased.

Thank you.
