MP4 Recorded From Air Cam Live Won't Play

[videoquestion]

Air Cam Live is an app that runs on your PC that can be controlled by your iPhone. It records video from a webcam connected to your PC in MP4 format. I began recording video on my Windows Vista PC, but Air Cam Live crashed and shut down mid-recording. I've recorded video before with this program that plays correctly, but this particular file that crashed mid-recording won't play. When I attempt to play it, an error appears that says:

"Error -2048: Couldn't open file filename.mp4 because it is not a file that QuickTime understands."

It's an important file and I'm hoping I can recover its video content somehow. I know the data is there, because the file size is 134mb. Is there any way to salvage this file?

probably not. but there are programs in the tools section/repair that you can download and try.
