It's been sitting on a shelf for a while, but the batteries are fine, but my camera doesn't load properly: I stick in a new roll of film, close the cover, it loads, but when I turn it on I get a code on the LCD: CA Then a couple seconds later it rewinds the roll. I can't find anything about this code in the manual or on-line. Anyone know what it means or if there's anything I can do other than take it in for servicing? Thanks
