Good day all.
To me and my mother the following issue happens to our Dune 2000 Gruntmods Edition clients - opening the Gruntmods launcher works, so does multiplayer of any sort. However, trying to open a mission in the Mission Select launcher or the campaign mode as a whole leads to it attempting to load (screen goes black for loading) and then it closes immediately with no error message of any sort, back to square 1.

What to do, what to do...
