Avi.net loading video problem

I have just installed avi.net and am trying to use it. I have .net framework 2.0 and .net framework 3.5 installed. I have also installed the required tools Avisynth, AC3filter, Vobsub and XVId. Now the indexing of the file works fine which I have tried using index.net. When I try to open the first vob file avi.net stops loading the video with an error that it has encountered an error and requires to close. Any idea what could be wrong?

Have you checked their website for support via e-mail? They have a “problems” section…
