Error code 630?

I was able to play the beta, but during the first mission after the tutorial my screen went black. I had to close and relaunch into the private beta, but I kept getting a error saying that the servers were full. Now to make matters worse instead I keep getting error code 630, and it says to look for a solution to error codes on the official site(but there isn't any such section here). How do I fix error code 630?

Servers are down at the moment. Keep your eye on their twitter for when they are back up.
