Now it works well. Thank you so much Martin! Have a nice weekend.

Hello. Thanks for your answer. I updated the license but it doesnt help. The issue is the same.

I started the video push the pause button and wait from 20 to 30 seconds. And the error begins. Its not nessesary to pause the video. It may works 30 seconds and get error again.

Here is the screencast of error – https://youtu.be/vmQLGZjdHug
