ZombieMod 4.0

Hi,
After some messing around I finally got the mod to work but I can't get the fog to work at all.

If I disable zombie_dark then there is no fog whatsoever
If I enable zombie_dark and zombie_fog then it crashes with the message "Classname missing from entity!" when I try to start the server
Does anyone know what this means or what I have to do?

I'm trying to run a listening server on win XP pro.

I really want to get the fog to work cuz it's such an important part of the zombie-theme

Thanks in advance

Ah yes, at the moment thats a bug with the listen server.
Install it to a dedicated server running on your own machine and it will work fine, then just connect to it like a regular server =)

I see, well thanks for the help
