So, I put the MarioKart Channel on my Wii, and now I can't go online. I don't know if the two are related, since I didn't try going online right after I added it, but even now that I've removed it and tried resetting up the online settings, MarioKart won't go online. It gives me the error code 20100. However, I *can* go online for the Wii Shop channel or whatever. Is it just MarioKart that's down, or is something wrong with my game now?
