Have you moved your payment method also? From US CC to Europe CC?
If everything still functions and the payments are going through I personally would not worry about it until your subscription nears its renewal date.
If that doesn't work or you have some type of problem using or paying for the subscription then you will need to contact Adobe directly at the link below and stating you have a billing problem/request.
In the US account, you can only select a US address (I want to change my payment credit card a Dutch one). So I have canceled my US subscription in the US. Now I have to wait for it to expire to renew in the Netherlands. When I login in the NL Adobe site, it still thinks I have an active account. Or I'll switch emails.
