Steam Key issue

This is for admins only, So I had the game when it was in beta/browser, stopped playing and came back to see that it was on steam only, so i went to the tab where i could get my steam key and it said it had already been used. The account is registered under this email that im using for this forum account.

Can any staff help me?
