Flash doesn't flash, space songs don't play smoothly, or the verification code keeps going wrong. Please don't worry. I suggest you refresh the page several times or empty IE cache.
Specific operation: Open IE and select Tools on the menu bar-> Internet options-> Delete the file, then select Delete all offline content and delete Cookies at the same time, and click OK. If the above operation is not solved, please try again later, and the system will be fine after the update.
