Hello,

I've searched for this error (Please try again later. [ref. #game-in-vault]) and found the following suggestions, all of which did NOT work:

• delete Origin cache
• open Origin in web browser and try adding DLC there (done in Chrome, Opera, Firefox, IE and Edge)
• try adding DLC via store, not game page

None of it changed anything. I am trying to install the free DA:I multiplayer DLCs. Every other DLC and the base game downloaded and installed without a problem. 

Does anyone have any other, possibly helpful suggestions?

Thanks!
