I have the latest Mountain Lion 10.8.2. My Server App 2.0.23 won't update to the latest version 2.1.1 via the App Store. It's as if the App Store is not aware that the App is installed and running on my machine! If I go to the App in the Store there is an option to buy it. All my other apps in the store do not have this option and instead say "installed". How can I make the App Store realize that the Server App is "installed" on my system? I assume that there is now no other way to update it other than the App Store, right? Please help! Thanks.
