I put my Lexar SD 2Gb Premium 60x memory card into my Nikon coolpix s202 and an info bar pops up saying my "memory card is write protected." It worked fine for the few months that I've had it. I received both of them as a present for this past Christmas and now experiencing problems. I have ~100 pics and ~15 minutes of video stored on the card. It hod 500 pics and 30 mins. of video. What can I do to get it working properly again?
