Saved mission error - initMission.sqf not found

[Mordan 10]

Hi all,

Trying to make a mission from the included missions, Dogs of War.

I have extracted the pbo and then used the editor - synced it - then did a send by email to save as a .pbo file.

I then placed that file in the mpmissions dir on the server and get an error when I start the mission I get an error saying "Script initMission.sqf not found." This results in me looking at a map with no objectives.

Anyone know what I'm missing here?

Thanks in advance.
