Okay, I own a Cannon Power Shot, less than a year old. It suddenly stops working and won't let me take pictures becus the memory card is locked. I took it out and locked it and unlocked it. Still. I opened the battery socket and cleaned it. Still. I blew in it to see if there was dirt or something making it. It worked, but the inside of the lens were fogged up and i could take as many pictures until i turned it off. I tried other memory cards and it says the same thing. I put my current memory card in another camera, but it works fine. HELP!!
