I am having the hardest time finding a way to download the new expansion. I already have premium, and the download did start on its own after the game downloaded, but I interrupted it. Since then, I cannot find a link to begin the download. I only find links to purchase it. Please advise.
What console?
If you go onto the main menu, and click store you should see the option to download it again.
If you’re on PC, perhaps try checking the account area of Origin might?
Pc
In origin, right click on battlefield 4 and click check for updates.
That didn’t seem to work
Im having the same problem on PS3. Got premium and ive found a place where it says download china rising, but the file is only 100kb large? download that anyway, nothing 
when the expansion came out on the 16th i think it just started on its own again.
This is true. its all been resolved for me, thanks
