Packs not working and saves not opening?

My EA app says that all the packs are installed, but they don't work anymore. In the game it says that they're not installed, but in the app it saysa they are. I just merged my EA and Steam accounts, and now none of my saves are playable, as the packs don't seem to work. Since it wasn't working, I then unmerged my EA and Steam accounts and still have the issue. I don't have the CAS demo installed.
