Yes I have my current installation from CD - I took a basic free trial online, then bought Limewire Pro from Limewire.Com, waited for the hard copy to arrive and installed it.

But what I do not grasp is the exact meaning of a "once and only payment".

I appreciate that when you buy software advertised as such, the white heat of technology's cutting edge moves on and newer versions and upgrades can cost development money that require an upgrade fee - because the product is perhaps no longer the same product that you paid alifetime usage fee for.

BUT BUT BUT

Surely, any company would respect it's loyal customer base to offer a cheaper upgrade route than the cost to totally new users?
