If video playback fails, adjusting your computer settings can often
remedy the issue.
Please try the following solutions:
Since changing browser or security software settings can affect how you view
other sites, please do this at your own risk.
Also, how settings are changed differs between software and browser versions
so please see each manual for further information.
■ Refresh the page multiple times or avoiding peak traffic hours (at night)
■ Make sure your computer date and time settings are correct
■ Use a PC that meets Niconico's system requirements and/or a separate browser

As each browser is different, deleting these files may erase the video player's stored data.

■ Change Internet Explorer security settings
■ Uninstall/reinstall Adobe Flash Player
■ Change security software settings
Note that some security software restricts access to certain settings.
Please contact the software provider for more information on how to configure software settings.
