I’m using the paid version here so I don’t know if this applies to the free version. Answer (1 of 6): Download 4k videos from YouTube Rapconverter has this feature if you can download you-tube videos in 4k hd format. I never had to do that before but decided to give it a shot anyway. Today I got an email back suggesting I log into YouTube with the program. This is my information that was automatically sent in by the program: If you don’t go through their app, send an email to Include screenshots of problem and Smart Mode settings, application version (go to Help then About), and operating system. So I described my problem to them and attached the following screenshot. This automatically opened my email program, Thunderbird, with an email ready to send. I clicked on Help in the top menu and clicked on Support. The other downloaders on my system were working so it was a 4K issue. I tried different videos, restarting 4K, restarting my computer. It kept showing the word Error with a red triangle by it.
