DVD Ripper 8.0.5.6 DVD Ripper Crashes Every Time

[mpj123]

I'm trying to back up my dvd's to mp4 on hard drive. I updated to 8.0.5.6 for Twilight Eclipse. That worked fine, but now DVDFab crashes whenever I try to back up one of my older dvd's.

I'm running windows 7 home premium 64-bit on an Intel i7 CPU at 3.07 GHz with 9 gb of RAM.

Here is the info in the popup window when it crashes:
