From time to time we see an increase in the number of issues people are encountering when updating/purchasing/in app purchases on the AppStore.
Please keep in mind that some of these issues are traffic related and simply require a little patience. If patience does nothing, we generally recommend:
-Signing out of your Mac App Store account.
-Restart your computer.
-Once your computer restarts, log back into your account.
(Times required for downloading differ depending on your internet connection)

Thank you for your patience.
