First: You download cf again (give you a method, you take out its installation package, uninstall cf, double-click the installation package to reinstall it, or go to official website to download it).
If the above methods are not enough, that is:
The firefight is updated frequently, and every time it is updated, some new content will be input into your computer. Every time you type, your computer will "collide" with it (which is also unacceptable), and Tencent will often exchange fire with "security updates", that is, fix loopholes. Maybe it will be ok one day, wait for the update. )
If the update still doesn't work for a few days, then there is something wrong with your system. Please reinstall the system. If you are from windows XP, please install windows 7. If it still doesn't work after installation, there is something wrong with your computer hardware (maybe your computer has some malicious software that causes hardware damage). Then it also said: it's a pity that your computer can't play cf!
You try to do as it says. If the hardware damage is eliminated, it can be repaired!
Wish you success!
Thank you, if you think it's ok, please adopt it!
Typing is so tiring, ah ah ah ah ah ah ah ah!
