The JVZoo Customer Portal where purchases are stored is a separate website from the JVZoo Affiliate platform. Having a customer account does not create an affiliate account.
If you want to be able to link your new affiliate account with your purchases so you don't need to login to each account individually be sure to use the same login email address when registering your new affiliate account as you use for logging into your purchases.
Register a new account as a seller or affiliate here.
