On your step 9, I think GoDaddy updated its control panel a little. Log in to your GoDaddy account, select My Hosting Account, then DataBases / SQL Server to list your database(s). That's where the pencil Icon is on the right side of the page. Once you select this, there are several icons across the top of the panel like backup, restore, description, password, CONFIGURATION, dsn and asp schema. This is where you get the connection string you need for your web.config file.
If, instead of selecting the pencil icon for your database, you select the link (Open Manager), you will be able to connect to your database (presuming you've remembered your login and password).
You then navigate down the connection to your database and then to the tables in your database. The second table is aspnet_Membership. You can open it by selecting the third icon from the right site of the page. Select the pencil Icon for the record you want to change - hopefully it is the only one in the table. A form is displayed for you to change. Make sure the IsApproved box is checked (I wouldn't change any other field).
By using the connection string you should be able to log on as administrator.
Good Luck
