"Error. Press shutter release button again"

i dropped my camera in a cushioned bag and didn't think much about it as i survived a car crash with my camera. i keep getting this error, after pressing the shutter-release button repeatedly it would go back to snapping pictures.

but once i want to use the "Live" function, it starts giving me the same error again. i have taken out my lens, using manual mode, the lens & shutter are moving swiftly. it's not stuck or lodged in any weird way. but when i go to "Live" mode it freezes up again. help.
