Unable to load mission..This missioin requires......
 

I keep getting this error when I try to load a mission that I have made..."Unable to load mission. This mission requires assets or an expansion that is not activated."

Ive hit updates, ive created maps in nile and med and have them all in dfx folder and they show up in menu, but i get that error when trying to play them or test them.

Any ideas?

Wow good question. All I can think of is that you need to check everything in you "General Information" In the MED...No terrain? No player spawns? Never had an error like that? is it for all your maps or only that one?

Maybe you should try rebuilding it from scratch if its small and in the beginning of building?
