China rising not working after pc format and copy of game folders

Hi

I bought BF4 digital deluxe edition which includes China Rising. I have yesterday formatted my PC and due to the entire game being almost 30GB I copied the game folder C:\Program Files (x86)\origin games\Battlefield 4 to a HDD and after reinstallation of windows copied it back. BF4 normal maps works fine and when I go to Origin I can see the expansion is there but when I try to join a server with China Rising I get the message that I have not purchased China Rising.

I have pressed the repair installation but no effect. Any ideas ?
