Trouble with packs through Steam and EA

I recently got a new gaming laptop and was attempting to download the game and all my DLC. I first tried downloading through EA app first and all my DLC purchased through them downloaded just fine but then my Steam purchases said deactivated. So I uninstalled and tried again but downloading on Steam first. Just for it to do the same thing but the opposite packs, so my EA DLC were showing as not installed even though they were. I've tried four or five more times uninstalling and reinstalling but still nothing has given me access to all of my purchased DLC at the same time.
