I have a prospective buyer for my brand new CD8454. I've been trying to sell it for awhile and kinda gave up hope on selling it. Sooooo, this upcoming weekend is when I was going to install it so I figured I may as well register for the E-iSERV. Now that I got a reasonable offer, I want to sell it but don't know if I can 'unregister' the E-iSERV. Anyone know if it can be done? I don't want to sell it if it'll be a problem for the new owner.
