My computer is doing this with all my cards... It shows them up but when I try to access them it just tells me to Insert an SD Card, even though the SD Card is showing up and nothing is loading... I say I should try and update my SD Card Reader Driver... It was working fine before I restored my PC... So I'll try and see where to find the Reader because I don't see it in Device Manager...
EDIT: NVM I found it, but it's at the latest version... so IDK... ._.
