There can be many reasons for this problem. For example, the player's PC can be infected by software which spams by injecting the library file into the game process or some players can blame Gepard Shield in order to force the admin to remove it and use cheats without any problem(I even saw such cases).
As you can see in the second topic from your first post, the game client works even better with Gepad Shield. It fixes the code of 2017+ EXE versions.
As far as I understand, we talked on Skype about this yesterday and you received new files to test. So, it is better to continue our conversation on Skype. I rarely visit the forum due to lack of time.
