I was using the new cooled camera tonight when i was about to shoot some darks when up came this messege on the screen and would not allow me to shoot Err 99 shooting is not possible, turn the power switch to off and on again or re install the battery, i was using ac power at the time ,followed these instuctions several .many times even changed to battery power but no changes,power is still on ,liveview is working ,menu etc just no shutter and the cooling unit is working fine , anyone got any ideas what this could be iam stumped.
