are you changing to a different account (with different banking info completely) or just changing your primary contact address? If it's the former, unfortunately you *will* see a hiccup in your service in that your old subscription will be automatically cancelled by PayPal and you'll have to resubscribe. The good news is that this isn't an automated thing on our end, so we can work with you to ensure you EBSQ account isn't closed.
If you're just updating your primary contact address, what Loretta said is perfect.
Get out of the vacuum and express yourself!
