2Wire: I can't redeem my code

Well, I was going through my recent players, and my Xbox just froze, I turned it off and then back on, it tooke a while to sighn in, it said it couldn't connect, I tried unplugging the router and plugging it back in, reconnecting to my 2wire, ext. so basically,
for some reason, it can't connect to the 2wire that I have, but it's only my Xbox that can't connect.

Modem and router are

2Wire 3800HGV-B

wired connection

Can't process the update. If the problem persists, go to xbox/support.

Status code is in the subject line above

It was a redemption code for a specific code, and I see that I have redeemed it on my microsoft account, but I can't redeem it on my xbox, I can't find it there either?

So the URL you gave is how I actually redeemed my game, but where I should I find it on my xbox then?

Thanks already.

Hello, i got my code in my xbox messaging app and was going to redeem it last week but the message with the codes seem to have disappeared. i can't find the message with the code to redeem the game.

Hey KingMaxKiller! This can happen if your region is set to a different location than your physical location. Double check that they are the same and let me know. Thanks!
