Marty here, from Shopify support.
I am happy to hear you just launched a store with us. However, I understand after making your first sale, your store became inactive. I can certainly see the need to reach out to us to look into this with you and I would be happy to help you out with this moving forward.
It looks like we’ll need to access your account in order to resolve this issue. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit our Help Center and log in to your account to create a support request.
Since this is the next step I've marked this reply as the solution for the benefit of others who may discover this topic. Thank you for reaching out to us!
