I can only assume that you were indeed logged in when you looked for those menus (as a host?). 

That aside, this is something that used to happen sometimes in prior versions of DNN, especially right after an installation.  I suggest logging off, and then log back on.  If that doesn't work, aslo try refreshing or clearing the site cache.

Is the account you're using actually a host account?  I know it may sound like a bad question, but I have run into that before.  You can further verify this by querying the Users table in the database, and making sure that the IsSuperUser field has a 1 (true) for the user you are logged in as. 

For instance, if the user you're using has the username of "jdough", just perform a query like so:

SELECT [IsSuperUser] FROM [dbo].[Users] WHERE [Username] = N'jdough'

The value should be 1 or true.  If you find this to not be true, run this update against the database (making sure you change the username and back up your database, of course):

UPDATE [dbo].[Users] SET [IsSuperUser] = 1 WHERE [Username] = N'jdough'
