oh, hmmm not sure wot that is then, there is a nintendo website where you can enter the error codes but im not sure what it is, ill try n find it for you
http://www.nintendo.com/consumer/ you can enter error codes here, but when I entered 61070 it gave me the answer "nul" hm not much help, sorry
Um, I'm not too sure. Do you have the internet channel? And if so, is it working? My first guess was that your internet connection isn't too good, but you said that the shop channel works. It might be a problem with the game (slight chance). I will look into it, and report back if I find anything...
something is wrong with your internet connection so you have to fix that, what my friends do about that is turn off the wii turn it on and wait like 3-5 minutes before going into the internet channel or game
