Call customer care 1-855-463-9333 there have been know issues with it not letting you log in after the migration. They can do a pass reset from their side and then you should be able to get in. Also they can help you setup your apple devices. I don't remember the server settings off the top my head. I think if you go to go.wildblue.com they are there though
