Please first make a backup copy of your registry as described here: http://windows.microsoft.com/en-us/windows/back-up-registry#1TC=windows-7

Next check out these steps below:

1. Log out and fully exit Origin
2. Open your Registry Editor - Type in regedit on the Start Menu Search field and press Enter
3. Navigate through HKEY_LOCAL_MACHINE > SOFTWARE > Wow6432Node > EA Games > Battlefield 4
4. Check if there is a folder named Xpack1 under Battlefield 4
If YES -> Click on Xpack1, on the right pane check if there is a string named Installed, the Value data should be True
If NO - right-click on Battlefield 4 > New > Key
- a new folder will be created, name it Xpack1
- right-click on Xpack1 > New > String Value > name it Installed
- on the right-pane, double-click on Installed, set Value Data to True
5. Exit Registry Editor
6. Log in to Origin and Join China Rising Maps

(Do the above and replace with the following for each DLC if needed)

Xpack0 = Second Assault
