Hello Rostas and thank you for the report.
Could you please attach contents of C:\Users\*USERNAME*\AppData\Local\DayZ to this ticket? Make sure you run the game with -dologs parameter so additional crash dump is created.

I put the screenshot with the error and also uploaded the stuff from Appdata. I can't upload the .mdmp because it says the file is too big.

Hello Rostas.
Could you try to compress the .mdmp file and try to upload it for us somehow?
Regards,
Geez

It was 20 mb. I made it into a .rar but it's still 5 mb and it doesn't let me upload it. I don't know how else to compress it.

Hello Rostas.
Would it be possible for you to upload the file on some kind of cloud site?
Regards,
Geez

I'll just upload it to dropbox. Here's the link.

Thank you Rostas.
We will look into it and return back to you.

Geez
