Custom missions not working v.1.201d

[Siipiorava]

I had installed some Veteranenmission packs before the patch and now I can't get to them. When I go to the missions screen I see the mission there, it tells me "The mission description is loading", But when I try to start the mission nothing happens. I have tried launching the missions both in online and offline mode, but so far nothing has worked. Is there a quick fix to this issue?

If this a repost of a existing issue please direct me to an existing thread.

Delete all files *.msnbin in the missions directory.
