Why does this problem appear?

Если при запуске игры на экране ничего не происходит, но звук есть, то причиной проблемы является сбой запуска декодера либо огромные потери на линии связи.

What should I do?

1. Install the most recent video-card drivers for Nvidia, AMD Radeon, and Intel HD, and reinstall DirectX 9.0c (download only the directx_Jun2010_redist.exe file, 95.6 MB). 

2. If there’s still a problem, you need to switch your decoder: press Ctrl+F2 and select Video decoder—software in the window that opens.   

3. If the image still doesn’t appear, then change the following values:  

Reduce video-processing quality to Very low.  

Reduce video profile to Baseline.   

4. If these recommendations didn’t help, contact our support team to solve the issue.
