Ok, quick question; I got my Wii today, and started to set up a wireless connection. I got through this fine, it detected the connection fine. But when it requested a system update, I said OK, it downloaded about 75% and now it's frozen. I just want to turn it off so I can deal with this later, but if I turn it off will it mess up the system since it's halfway through an update? If it safe to turn off? Help me!
