Canon 5D & Istop motion 2 not working

Hi - Ive got a Canon 5d Mk2, Istop motion 2 and working on Macbookpro OSx V10.7.5 and its not working. Used to have another digital video camera which worked fine but with the 5d nothing is happening - can someone advise what I need to do to make it compatible? many thanks Barbara

It may be the problem, that the Canon 5D wasn’t introduced in 10.7.5 and therefore the system won’t talk to the camera the way we need for iStopMotion. Can you please try to capture a frame with the “Image Capture” app by Apple? Does this work?
