Trouble loading custom made multiplayer missions

[bsd13 10]

I'm running a dedicated server and have no problem getting included missions to run, but I can't get a custom mission to run.

I connect to the server, see it in the mission list, select it and wait for the countdown vote timer to reach zero but it doesn't go beyond that. Myself and other clan mates are able to run it via our client machines using them as servers but not on the dedicated.

The person who sent the mission to me just sent a .pbo file that I've placed in "MPMissions" folder. Am I missing a component or something?

Thanks.
