A friend went on vacation and took pictures. Someone "helped" her and said "I'm gonna protect the card and the pictures". Since he "helped", she cannot view the pictures; she gets a message that says "protected card", and then "card error". Can this be resolved and the pictures recovered?
Check to see if the "lock" is set on the card. It is a little tab that slides on the side of the card. If it is in the locked position, slide it in the opposite direction to unlock the card. This is the only thing I can think of that would cause the problem. Hope this helps.
