Q: What can I do to fix these errors?
Video preview is not working. Plus, it says when I try to download, select a folder, and then it says, "Sinosentdcannot open it because it's a system folder."

Video preview, depending on the size of the file, you would be better to download the video.
We are not a video streaming platform. You can preview some videos by hovering over the video player, and will start to buffer.
The download link is not broken, that is how the new browser streaming file api works. You can only select a folder that you create, you cant select your system folders or windows Download folder.. To solve this, create a folder where you want to save your files, and it will stream the download without zipping, keeping the folder structure intact. If you have Safari or Firefox, we will fallback to a zip download for multiple files.
