Registration product

Hi!

I am writing to seek assistance regarding an issue I am experiencing with re-registering my Pioneer product. I previously removed the product from my old AlphaTheta account, but when attempting to register it on my new account, I receive the following error message: "Entered serial number is already registered.

I kindly request your support in resolving this matter so that I can successfully register the product on my new account.

Thank you for your assistance.

Best regards,
Hanna
