Hopefully you've sorted this out by now, but if it happens again, try logging out of Admin, then log back in again.
In case you have more than one E-junkie account, remember you can only be logged into one account at a time in the same browser program; i.e., you can't be using one account's Admin in one tab/window while using another account's Admin in another. The last account you log into will "take over" your login session for all windows/tabs in that browser. If you have a need to administer two accounts at once for some reason, you can use different browser programs for each account's login session (e.g. log into one account with Firefox and the other account with IE).
