The pack I purchased will not show up

It did work but because my game is ran by steam the pack did not show up.

@_yuliana60_   Ugh!  Have you tried launching the game from Steam instead of the EA app?  If that doesn't work either, at this point, I wonder if it might be better to uninstall the game entirely and reinstall it through the EA app.  You may first want to make a backup by copying and pasting all your content to another location on your PC, either on your desktop or create a new folder. This is just so you don't lose any saves / content. 

Currently I am downloading sims 4 with EA and I have put all of my cc and other things from the sims 4 file in one place, how would I be able to add them all back when the game is fully downloading.

@_yuliana60_   Apologies for the delay.  My eyes were closing by themselves and I had to crash.  I also think I got a bit confused because I was so tired.

I want to make sure that you don't have any packs that you only bought from Steam.  If you do have packs that you want to play that you bought from Steam, then you'll need to continue launching the game from Steam,  Steam-owned packs only work with a Steam install.  EA-owned packs work with either one, or at least they're supposed to.  Did you try launching the game from Steam after buying Seasons?

As for your game content, it will be easy to just move it all back in once the game is fully installed.  It actually might be better to do what's considered a "factory reset".  See the below link for instructions.
