Read this somewhere else and it worked for me too. Click on payment options and you'll be asked to log in. You can cancel out once logged in on payment options, then go to "My World" again fine. I hope this works for you.
Listen all you have to do is keep trying to get into the payment option and eventually it will give it to you that was my problem it would just give me the same error but when I gave it a couple of trys it went thru go in then when you're at the payment section already just hit cancel and go back to the applications and it should work already good luck
