Account closed

Hi,

I created a test account for myself when setting things up. Now that I went live I deleted my test account. When I now access the dashboard when logged in as admin I get the error that my account is closed (so no form to register, just this message). I tried using another browser to register again but I get the error that username and email are already in use.
However, when I check my affiliates in the backend, my test account isn’t listed anymore. Am I missing a location somewhere to “deleted accounts” I can reinstate or is there another way to solve this?
