Ok, i think i have finally resolved my problem. I started to switching my RAM chips suspecting it might be caused by them but it didn't help a lot. Then i started to deeply inspecting my operating system, i found a lot of corrupted, missing or duplicated files, damaged registry, memory diagnostic wasn't working at all. Propably all this mess was due to my disk change few months ago. I migrated my system from old HDD drive to new SSD one, and i think this caused all this mess. I installed fresh copy of Windows 10 and for now i played more than hour without any errors, i hope it will stay like this.

Still the same thing :( im starting to lose hope that i can manage it to work somehow. Also im thinking about upgrading my system to Windows 10 but i want to do it if there will be no remaining options.

Hello,
Thanks for your fast reply. Sadly this solution didn't help. I joined the game and after 10 minutes of playing problem still occurs.
