I have a sky3ds (blue button) that does not recognized the microSD card when plugged into a PC (this has been a problem for 6-12 months).The card is recognized by the 3DS and the games on the card are playable, but I am unable to load any new games onto the card. I tried two different usb microSD card readers and even tried an SD to microSD adapter, on two different computers. Does anyone have any info on what the problem may be? At the time the problem started, I had the most recent firmware and necessary programs. Thank you!
