I have a Canon A80 and it was working fine for the past 2 years. Now, suddenly the camera doesn't power up after I insert the memory card. It powers up fines once I remove the card. I tried with many diffrent Compact Flash Cards and also new brand new batteries, but all in vain. Does any body h ave any suggestions what would have gone wrong? The camera has never been dropped and looks brand new. I am not sure if this is related to the E18 error that canon camera holders experience.
