I get only a black screen when selecting a webcam

Post from @Tea_Dora

I have the latest manycam version. When I try to turn it on I get only a black screen and not a video, while my camera light is on. This happened after the windows 10 update.

Hey @Tea_Dora

I had to move your post. Please install the latest update: https://manycam.com/download/

If the issue persists, post a few screenshots to illustrate your actions step-by-step.
