Hello,
you are right. There was a problem with my sound card. Producer of my mainboard published new BIOS and sound drivers. BUT... after upgrade there is still the same problem... I tried disable default mainboard sound card and plug external one (usb sound card), but game still crashes on start.
I've uploaded new crash files:

Can you check if (BIOS and sound drivers) upgrade changed anything ?
Can you ask "programming department" for more debug information about this "bug" that I could forward it to my mainboard producer?
Thanks for help.
