The actual video file does not download from the browser or by direct URL. In some cases, Jaksta downloads hundreds of files from the single webpage/URL.
The log file you sent is a bit hard to read in a Word doc, so it might be best if I can generate my own to look at.
Can you please supply me with a URL link to the video/site so that I can test it?
If it requires login credentials can you please send them privately to firstname.lastname@example.org, so long as you are comfortable with it.
