I bought $20 worth of Wii points on my brother's Wii thinking it would attach to my account, not his Wii. When I got home I realized I was wrong. So I'm trying to get him to gift me a game but it tells us we need to register each other first. So we both went into our respective message systems and registered each others' Wii numbers but that was 3 days ago and we still can't exchange messages. It reads, "You must register one another to be able to exchange messages." We checked our Wii numbers 3 times, they're correct, what else do we need to do?
