I am hoping someone can give me an idea of what is wrong with my camera. I bought it at the end of last year and have taken 2800 +/- pictures with it without any problems. Yesterday when I turned it on I got an error message telling me there isn't a memory card in the camera. I took the card out tried wiping down the contacts on it but nothing changed. I tried a couple of other SD cards and got the same message. I took some pictures five days ago and everything was fine. Is there a possibility that a setting got changed? If so I did it inadvertently but I'm hoping that is what happened. Since my camera is only six months old I still have a warranty, I just don't want to mail it off before I make sure that is necessary. I appreciate any help.
