can’t set the source file

Hello bruner,

Thank you for file you have sent us to support. We will shortly answer to your email.
Thanks for patience.

I have downloaded and registered the trimmer to use with trimming portions of a video from a DVD.  I keep getting the error “can’t set the source file” when I attempt to trim a segment.

I need to be able to get this to work as I need the trims for a presentation tomorrow morning.
