I was out shooting this morning and took one shot and moved on. About 4 minutes later I tried to take another shot and the meter was way off. I was using live view the previous shot in manual mode. Now my camera still functions, but only in manual mode. Aperture priority, program auto mode, U1, U2 etc all give an Err message. Also I can no longer use the flash as it also produces an error. The meter is way off as well unless I switch to live view and back again. Every time I shut the camera off and turn it back on it has metering problems. Need some quick help as I am on holiday in Spain and I have a camera that is barely functional.
