ok i downloaded the mpsa file from the link you provided but the mps file from the page only leads you to an error 404 page where you cannot download it, i decided to get the file from one of my other working server files which had the same one, then i copy/pasted them into the mods folder in the server folder and ran launch.bat and now it does not have a severe crash error, it simply wont work, all i get is this and at the end "press any key to continue"
I am also gonna add that when i installed the new mpsa and mps files i downloaded a fresh copy of the server folder from the technic site
