import images from a still camera (Kodak C613)

I am having trouble getting any images to import from our camera to iStopMotion (Version 2.8). Whether I select a single picture/image or select all of the images collected on the camera, the pop-up screen shows the image(s) are being imported, but nothing ever happens. It takes so long for 1 image to be downloaded, the camera goes into battery saver mode and shuts down. Please, any suggestions. Sadly, we purchased tthe download of iStopMotion instead of using the demo version to see if these problems would arise.

Our camera test list says that it succeeded in “PTP-mode” for other customers, so please set it to that mode if possible.
