My kids & a couple of friends tried to get this game going via download play, but couldn't get it to communicate between the DS consoles. I tried to send it from each of the 4 consoles, all gave the same communication error (the game recognizes the DS but eventually fails after 1 min or so of downloading. Is this a known problem with this game? Note: Sorry if this has been discussed before, but its impossible to search the topic (try searching LOL!).
