So, please uninstall your player completely first, and then install it again, refresh your webpage, and try again. In addition, the Video Library player doesn't support Firefox at present.
• Why can't the video play fluently?
  First, please close all the download tasks.

Increasing your network bandwidth will solve this problem, please contact your network provider for more details, for example, China Telecom or China Unicom.
