The File Type is not supported

Hi bppilot,

Thank  you for contacting us.
Say please if WMV files are displaying in  Windows Media Player itself?
Could you please send to  support@solveigmm.com a Screenshot of this error?

So I am trying to just change the start time and stop time of my video, but when I use the utility, it comes up with an error that says "File type is not supported", then it gives me a list of approved file types. The file is currently saved as a WMV, and it will not let me edit. I have since converted to an AVI and an MPEG and have the same results.
What am I doing wrong?
