Whenever I try to download videos, a window pops up after I copy the Youtube link on to the URL bar. The window says "We processed your links, but some videos cannot be downloaded for various reasons. These links were skipped. Skipped 1 of 1 links." It does not seem to be related to the resolution available since I can't even get to the part where I can choose the resolution yet. I paid for the premium of this software and I'm really disappointed that it isn't working. Please help?
