Ever since Origin was replaced by the EA App the Sims3 Create A World tool fails to properly launch Sims3 when you try to edit in game. I'm guessing that it is trying to send some parameters to the Sim3 app to tell it to open a specific file in edit mode. The Origin app obviously passed these parameters along to the game while the EA App must not. The solution would be to have the EA app pass along any parameters to any game that has to be run via the EA App. That would most likely solve the problem with CAW and if there are other games run via the EA App that have utility programs that trigger the game to run in a special mode would fix any similar problems with them.
