This Youtube Video won't download https://www.youtube.com/watch?v=qZ_8lJs12tk

Hello!
When loading the following URL into 4KD the initial "Download Clip" dialogue box shows a "0 b" length for all frame sizes.
https://www.youtube.com/watch?v=qZ_8lJs12tk

After selecting a frame size I click the "Download" button and immediately get an "Error: can't download" message from 4KD.

As an experiment I attempted to download the clip using www.clipconverter.cc where I receive a similar error. Thus it seems it may be something new that Youtube is doing...

Thank you for your hard work on a great program, and thank you in advance for anything you are able to do to solve this current problem.

Regards,
