When you zip it in hour main, it will automaticly make his own folder, and in that folder is the .pk3 you should copy in your main biggrin: hake:
I just realized. Don't put the zip file MTC you get into the main folder. Unzip the file with winzip or win rar. Take the Zzz-city_nights.pk3 file you find in the folder and put that in your main folder.
