A: Hello, we released a component update this Monday. Usually, you will get it automatically at launch.

Please confirm whether your component version is 2026.08.21.

If not, please restart your computer or the software to get the latest update automatically.

If you are already on the latest version, please try the following solutions.
Check VPN: If you’re using a VPN and the program keeps asking you to reactivate, disable it and test SurFast Video Downloader again.
Check antivirus: Some antivirus programs may block SurFast Video Downloader from functioning properly. Try temporarily disabling your antivirus to try again.
Clear Cache: Go to SurFast Video Downloader's Settings > Advanced Settings to clear cache. Restart the software. You can try multiple times.
Clear Chromium Folder: If no VPN is in use, delete the Chromium folder at the path below and restart the application:
Windows: C:\Users\admin\AppData\Roaming\NablaMind\SurFast Video Downloader - enter this in the File Explorer: %appdata%\NablaMind\SurFast Video Downloader
Mac: /Users/xxxxx/Library/Application Support/NablaMind/SurFast Video Downloader
Delete yt-dlp_macos (Mac users): Try deleting this if none of them works: /Users/XXX/Library/Application Support/NablaMind/SurFast Video Downloader/yt-dlp_macos
Check for YouTube Block: YouTube may temporarily block your IP. Open the Private feature and enter the video URL. If you see a captcha or login prompt, complete it to verify you're not a bot, then try downloading again.
If these steps don’t resolve the issue, please provide:

The Video URLs
Your SurFast Video Downloader and Component version (Settings > About).
Your OS version
The vd_server.log file from the same path above.
I look forward to your update to assist you further.
