This is sort of a strange contrast to my experience with the South Island Rangers. I've only attended one of their games, and I was admittedly not very good, but they were still very friendly towards me. I think I was still a little annoying, but when you make an active effort to follow the advice of the more experienced players, I think they start to realize you're genuinely trying to get into the sport.
My advice? Go ahead and ask the AK guys directly why they didn't enjoy having your friends along, ask how to make it better next time, then convey the message to your friends. Just like any sport, I think the best way to get the players to accept you into the fold is to take initiative and start heeding the wisdom of the more experienced and knowledgeable.
