8.1 Downloading issues on “Paste URL”
Question: Hi! I just downloaded your app moments ago. I am currently using the trial version because I want to see the credibility of the tool before buying it. So I tried to download by pasting the URL of the video, however, it won’t download when I click the “Paste URL” button.

Answer: Normally, you use the “Paste URL” button to paste the copied link to download it. Yes, that is right. However, you must also know the limitation of the feature. Sites have open source can only be downloaded through this method. If you are trying to download videos from Educational sites or Movie sites it won’t really work. This only works from sites that are less restrictive eg. Youtube, Twitch, Facebook, Instagram, Myspace, Rutube and a lot more. These sites are not encrypted. Moreover, it does not stop there, that is why auto-detect was developed to kill this limitation. Try downloading the video using the “Detect” tab instead. IF by any chance the video is still not downloaded, that means it is encrypted to avoid copyright issues

8.2 Downloading issues on “Paste URL” continuation
Question: However, I am just downloading videos from YouTube. There must be no problem, right? But the video is not downloading. IS there a way to fix it? Should I download it again? I will try to download and install the app I hope it works. I will let you know guys if the tool works after. But I hope to hear something from you, it will be a great help in the future.

Answer: If this is the case please try our alternative way of pasting the URL. From the main interface, click the second download button beside the “Paste URL” button.

8.3 Downloading issues on “Auto-Detection”
Question: I am downloading Movies using the Auto detection feature of the tool, but it suddenly stops and has a “red exclamation mark” beside it. What do I do? Should I repeat the download? Is there a way for me to continue the download without repeating it?
