"mpmissions\DayZSurvival.chernarusplus\mapgroupdirt.xml" Error. Am I missing files?

Hi there.

I'm trying to host a server but I get this error:

 

It says something about a "mapgroupdirt.xml" error. I downloaded the server files and followed tutorials, I think I did everything right and I have no idea why I'm getting this error. Can someone help me, please?
