No video ONLY audio

After spending money to upgrade to PRO I tried to convert my first file - an MKV. The sound converted, but NO VIDEO. I played the MKV file as it is on a video view program and it is fine. This upgrade is supposed to convert MKV files to MP4. Without the video it is actually converting to an MP3. If I wanted to listen to my videos this would be no problem, but I don’t think it is asking too much to watch my videos. This is rubbish and I want my money back.
