Unexpected content from server (got JSON)

I loaded PZ2 onto another device.  I then proceeded to sync to server.  It told me there were multiple IDs and gave me the option of which one to pick.  I selected the ID associated with the game I could not get to download (JSON) error.  It loaded my old game with all my current settings, I then went to iPod an uninstalled my PZ2 and reinstalled.  I then went in and synched the game and again it told me there were multiple games associated with my account.  I selected the User ID associated with my original game.  This fixed my problem.  Only took 3 weeks to figure it out.  EA help couldn’t help.
