Hi Robert, if you have downloaded and successfully extracted the file, then you should not have a problem with it. Odd the sound is distorted, usually people complain they can't see the video.
You could download the Klite Codec pack, which contains every codec you will ever need, and also gives you the option of installing Media Player classic, which is better at playing videos than MediaPlayer 10 and 11!
Download link is here:

I suggest downloading the full version, it is still free and contains all you'll ever need.
Hope that helps, and just an update, still no news from 1C or Oleg
Fingers-crossed though
Cheers, MP.
