Can't download China Rising

Hi.

The first time I logged inn while China Rising was active I had a full disk so I started to clean out some things to start download the expansion.

But I never got the download pop up again when I log inn. Now it just goes straight to battlelog. And when I I try to join a server I get a pop up saying you need to install China Rising, open in Origin.

So I open it in Origin but nothing happens. The download won't start..

Need help.

Best Regards
