VDownloader youtube download error: The error occurred during execution of task

[craz]

I'm trying to use VDownloader to download a youtube video and save it as mp3 but for every video I try it says "New download..has been added.." but the video doesn't start downloading and I get an error with "The error occurred during execution of task.."

I performed a test (help > perform test) and it downloaded successfully from about half the sites tested, but still had an error for youtube.

I tried disabling the firewall with no improvement.

I have downloaded tons of videos from youtube using VDownloader some months ago and it used to work perfectly. What's wrong with it now? Is anyone else having the same problem?
