Thread:Project:Support desk/Screwed up bigtime

Just had my wiki installed via Softaculus, version 1.8. Am a serious beginner. Siteground sent me a link to the wiki with a name and password. When I went to log into it, it did not accept those user id and password. So I created an account with what I thought was the same name and password. The group rights pages shows - wikimiddleeast (bureaucrat, admin) and Wikimiddleeast(user). Both I gave the same email address to. Now I can only log in as the user, not the admin. What can I do? Can I delete the whole thing and start over? Can I give the Wikimiddleeast user the same rights? Please help.
