i have an sd card in my wii. ive saved and downloaded lots of things over the last year or two. ive never had a problem with accessing the data on the sd card but over the last week i cant get anything off it or look at it. i notice the problem when i turned on the guitar hero games and none of my downloadable content is brought up in the game. it says that the device in the sd slot cannot be used? its the same card ive used and it worked fine not too long ago then just stopped and now cant be used? this is very confusing any help would be greatly appreciated. thanks, kristina
