So.. I'm trying to download some apps from app store on my iPad for the first time(i have had a iTunes account since earlier). It says "press continue to review you payment settings" when i do that, a screen pops up where I'm asked to enter my password - which i did. But it just does not want to log in, because the screen pops up again just like i would have typed it wrong. I can however sign in to the game centre - which in itself tells me that the password does work. Is there some special setting i should do while having it synchronised in iTunes?
