bought packs.. installed but don't work

Hey, so I've bought three expansion packs yesterday via InstantGaming and entered the code into the EA-App, they install just fine and I think I'm able to play with those but nooo.. in the building menu some categories get displayed as yellow, thinking there is something new but there isn't. And in the menu where u could change the worlds, I can' click on them. The game says, I purchased them but they needed to be installed but they are. The EA App tells me they are installed. I really wanted these packs and now this? I really need help here
