Hi Geez,
So I connected to the Oldschool Hardcore server just now, details following

Thanks Geez for the swift reply.
Oops, my bad, I´m not very proficient with software stuff, didn´t know that I had to make the folder visible...
To the task at hand, I have the latest NVidia driver installed, and verifying the cache didn´t fix the issue.
However, I noticed thet when I delete the DayZ folder from the Documents folder and then copy in the files from the backup DayZ folder I created, it won´t let me connect to server X even when I already tried to connect before deleting the original folder, if that helps in any way.
Cheers,
