@acidhax
thanks i just sent you the file.

Hi,
I Can't play videos anymore. I've watched a few shows fine but now it's not working!!!
I've restarted chrome browser, reset my chromecast (physically on tv), check my firewall settings, windows defender. But still getting error:
Oops!!! We don't think that's a video or a song!
I have a screenshot for you I will post if I figure out how to post photos here.
