At first, download and install the latest version of Origin at www.origin.com/download (and make sure you have your Origin account ready as well)
If that doesn’t helped, close the origin client and go directly to you origin folder C:\Program Files\Origin Games. Run the origin.exe in this folder with a rightclick -> run as administrator.
Then you go to the cloud button on BF3 and uncheck the “enable cloud storage for all games” box. Launch the game, quit it and re-enable the cloud storage box. Make sure to use the local data when the information box popping up. This should reset the Cloud Storage.
