I called EA and spoke to them about level 436 and up, he did some checking and said that the developers have not released the new levels yet and they probably didn't even intend for the new levels to be seen yet. He said to be patient, and wait for the new patch to be released. He doesn't know when that will be but it should be soon. He said no one is able to play those levels yet so reinstalling the game etc. Will not help, we just have to wait!
