Thanks for the sample. I had no issues in converting it so I had a closer look at your logs and it looks like may have a corrupted installed of MCEBuddy.

Some of the files like ffprobe.exe are either inaccessible or missing. I would recommending doing a clean install of mcebuddy and that should solve your problem.
