hi. i just went to best buy to purchase an sd card and a card reader usb so i could play online mario kart. i try to play on wiimmfi after downloading ctgp and i get an error. after looking it up it says i have to wait 7 days. it also says it says only for me when consoles but i've had it for over 5 years. is it an accident? i was planning on inviting friends over who didn't know you could play online. any response would be great
