I came across that last week for a client. And I actually had a new activation key, serial #, unlock key, and acct # - and the client was already running 4.5. I would have expected to only need to update the unlock key, and maybe the activation key. And this was actually the 1st time I've had to use the new Customer/Account # that shows in the Sage Portal. I'm wondering if all the reg info was re-generated (based on the new Customer/Account #) upon processing an additional purchase.
