Import the video into the program, and a video and audio, the lower of the two, tracks will appear.  Mark the file, so that it becomes red, then choose Ungroup (Ctrl M) ie with the two chain links separated. 
Place the cursor on the audio track, and if  only this is  now marked, you have successfully separted the two,  and can delete the audio file.
