Apparently this is happening because we don't have IOS245, which is used to install Mega Man 10. I have been having the same problem as you. But sadly, I can't find IOS245, and install it on my system. So I am at a total loss. The truth is, if I could connect to the wii shop channel, I would just buy it to save me the headache, but I can't. Does anybody know where I can find IOS245?
