I took some pictures last night and loaded them on my computer. Then found one wasn't good and retook it. When I put the memory card back in the reader and clicked to load it it said the card was not formated, I clicked yes to format when it asked and it said the program would not allow it to be formated. While I was loading the first pictures my computer froze up and I had to shut down and restart, when I did I unplugged the card reader. Did I do something to damage it? What can I do about this? Or do I have to get a new memory card now? If I could manage to send it to the company could they reformat it or what?
