Youtube players not working(Black Screen)

Hey so I have been trying to use a theater sever and I can hear the audio but I don’t see any of the images. I then downloaded PlayX and I came out with the same result. I have installed flash onto every browser on my comp. restarted my comp restarted the game client and also tried the trouble shooting tips for the addon. I still cant find what the error is. Any advice would be nice thank you

Yeah if you downloaded it from gmod.org. It’s corrupt
Well it’s actually outdated. I tried this too and I crash too.
Get an updated version.

thx do you know where an update can be found?
