my flash player didnot support such video and the version is too low

I have checked in your internet, it told me Flash Player is pre-installed with Internet Explorer in Windows 8. and Either Flash Player is disabled or ActiveX Filter is ON. But i really find  Flash Player is enabled or ActiveX Filter is Off. For flash play, it can play most of flash video, however, it shows my flash player didnot support such video and the version is too low. In fact, the my downloaded version is the laterest. how can i fix the problem? thanks.
