Hello, to open the next unit you must finish both the super gem and the missions. Click on the communicator to see what it says. If you have subscribed, but the game is telling you to go to the www site for a message, it is possible you subscribed under a different email address than the game is playing on, and if that is the case the subscription isn’t recognized by the game.  Email support@adventure.com with your possible email addresses, and then we can check for you and tell you the best way to fix this issue.  There is no way to do it without the Jumpstart Staff checking into the accounts.
