Actually, you only need one E-junkie account for all your uses of E-junkie, as there's no real distinction between seller vs. affiliate accounts. While you're logged in, you can use the Sellers and Affiliates tabs at the top of our site to pick which Admin panel you want to see at any moment. I went ahead and restarted the 7-day free trial period on your original account to re-enable your Seller functions there and let you set things up before you'd need to start a paid subscription to continue selling from that account.
That said, if you really would prefer to maintain separate accounts for your seller and affiliate activities, you can add a Confirmed secondary email address to your PayPal account and use that as the PayPal Email setting in your new seller account.
