I'm not sure how the MS Digital Image Library software works, but you should be able to plug your camera in to your PC using the USB cable, then you can browse the removable drive manually to see if you can find your video files.
If you're not prompted to browse the camera memory card when you plug the camera in, press
Windows Key + E and you'll fire up Windows Explorer. You can then navigate to the removable drive (probably the last drive letter) and copy your pictures/videos over manually. If you need to find just the video files, you could try sorting the files by size as the videos will most likely be the largest ones there.
It's not quite what you asked for, but as I've never used that software it's the only way I can think of recommending where you can be sure you've got the video files.
BTW - if you're looking for a replacement application, Google Picasa can import pictures/videos and it's a pretty good tool (and free):
