Well, when I was registering with one of my friends in person, we found that it works fastest if we register at about the same time. For instance, DSDude has had me on his list for weeks, but I just got him on mine due to getting my USB adapter, and it has yet to accept him. It was a similar situation with my friend, and when we both re-entered the codes at about the same time, it almost immediately registered.
