FH4 Not being able to connect with the cloud

I am planning to buy FH4 very soon so i downloaded the demo about two weeks ago, and for the first time it ran perfectly, i completed the intro without a single problem, but then i changed my Microsoft account pseudo to another email address and since then everytime on the Senna screen a window pops out and says “Unable to sync the data with the cloud, and it gives me option to try again, witch does nothing, or to” play offline ". Is there any solution to this problem? Will i be able to play online once i purchase the game?
