I logged into my shopify account. However, within the admin panel, it states that I don't have any store yet and shows a button to create a new store. When I attempt to create the store, it tells me that a store with that name already exists. I believe that I created a store with that name a few years ago when I wanted to test out Shopify. I own the domain name, which is registered through GoDaddy. How do I go about creating a store using that name when Shopify keeps telling me that the name already exists?
