Keyclone now asking to purchase an additional license?

[Maxim]

I've been using Keyclone for quite some time now, after already purchasing a license once... now the software is asking me to purchase another license, and I'm kind of curious as to why. I am assuming the claim on the website that one license for life is still valid? I haven't changed machines, but I did move within a 'Comcast' area. Comcast assigned me a different account number and upgraded my package, but I'm not sure why this would cause problems.

Edit: I did transfer my license and can use the program, I'm just curious what prompted the program to ask me to repurchase.
