We have been tracking this error code with the developers and are awaiting some more information from them.

So far what we do know is that it has to do with a loss of connection somewhere within the game.

Your best bet is to just check your connection to make sure its stable and try launching the game again. As soon as we have more information on this error code we will make the appropriate announcements.
