"Error 3: There was a problem. Please try again later."

Been getting this error every time I've tried to redeem my code (via Amazon pre-order) for the past 3 hours off and on. Some are saying I need to buy a new one for $3, others are saying the server is just being overloaded with procrastinators (guilty), so I'm not sure which to believe. Anyone else having the same issue, or had the same issue but was able to fix it?
