It is possible that Error 307 is related to changes that were made on the servers awhile back. Currently you are only able to log in to one Megaserver at a time. If you're playing on EU and then log in to NA as well, your oldest session will be kicked from the game.
There are also steps that customer support can help you with if this is not the case. If you happen to have a ticket number for your inquiry, we'd be happy to check into the status of it!
