Automatic Youtube Video Posts Plugin 3.3 is not importing any video.

When clicking on “Import” is get the following message:

“Attempting to download videos 1 through 50 from playlist: …..”

but it doesn’t do anything. I tried several times, I even uninstall it and re-installed it back again, but it is not working ??

Any suggestion please?

Thank you!
