I downloaded this level Hyperspace: Apotheosis but when I try to play it I get an MN3 error as if I don't have it.
It's in my missions folder and I can play it offline, but not in multi.
EDIT....sorry it says Error initializing game module.
I finally fixed it by reloading D3 and patching but I lost all of my configs. Thanks for the tip on the d3m files. I may have deleted them when cleaning my files.
