This may be a problem with the Kuwo sound effect. You can download it and re-download it. The download time will be very fast. Actually, I feel pretty good about being cool!
Another reason may be that there is a problem with your computer. The card or the monitor is broken. You can ask a professional to help you take a look. Supplementary answer It seems that you don’t know much about computers, right? If you can’t find that folder, I’ll teach you a way to definitely find the mv:
1. Open KuWo Music Box and select the desired mv to play.
2. Find the "Internet Explorer" icon on the computer desktop, right-click the mouse and select "Properties".
3. Select "Settings" in Temporary Internet Files in the pop-up window, and select "View Files" in the pop-up window.
4. Select the "Up" button in the menu bar of this window to return to the previous directory. You should be able to see the Temp folder. hehe.
5. Open the Temp folder and see the KMusic folder. Open KMusic and there will be the mv you are looking for, which is also named with numbers.
Be sure to open Kuwo Music Box to play it before downloading. When you play an mv, it's an mv. When you play a song, it's a song. It's very convenient.
