Problems downloading files from youtube

Hi, I'm tryping to download the video from http://www.youtube.com/watch?v=7QokSpFVHEw
but I'm not able to do this with Download Studio 7.0.5.0.

Can anyone explain me why?

I have bought Download Studio because I want to download videos from youtube.
In the past I was able to do this.

Hi, I just tried downloading this video and it worked correctly. Could you send the job conversation of this download to support@conceiva.com so that we can see what is going wrong?
