Error 10 message
The error 10 message is trying to tell you that the new memory card you have tried to put in is not compatable with your camera. AS you have already tried turning it off/on, replacing batteries etc, you can try taking all cards out, and attempt to get it to fuction correctly with original cmaera memory. After taking out all cards, and with a fully new set of batteries in, use your cameras menu to format the camera memory. Now try and take photos with just normal memory. Is it working? If it does, and error is gone, put in old memory card and reformat it. Does camera pick it up and recognise it. Can you now use it. The new card you tried to install may have been an incompatable brand. Check your manual for approved brands or your local dealer. The card could also be faulty.
