NVH Not Downloading Rated 3 out of 5 stars

I uninstalled NVH 1.9.4 and reinstalled 1.9.4 to fix the youtube, thatvideosite and soundcloud downloads issue and it still doesn't work. I am using Nightly 19.0a1. I tried it on 2 different computers and NVH does not down any videos or mp3s. I am also getting 2 downloads for the same video in the download box. 1 is the full size file and the other is few kbs of the same file. Please fix.

Thank you
