Freeze videos when playing with PotPlayer and VLC

[ramaflore]

Hi,

I can't view any video without freezing from the beginning till the end neither with VLC neither with Potplayer.

With Potplayer I got the following message:

Flash.ocx is missing.

I don't really know if this file is responsible of my freezing experience.
I downloaded from the net this file and I copied to the folder c:\Windows\System32\Macromed\Flash\

But still have the same error message when playing a video with Potplayer.

Any help would be welcome here, thanks.
