Okay guys, as a last resort, try re-installing the game, it usually fixes most issues (please note that any progress on the mobile device that has not been synchronized with Facebook/King account at this stage will be lost.

However, all the progress that is currently saved on Facebook/King account can easily be retrieved, once you have reconnected the device successfully). Regrettably, you will lose any saved messages. 

Let me know how it goes, please
