So I tried to open KSP and then realized I had not added the mod I just downloaded, so I force quit KSP before it was done opening. And then added the mod. Then tried to open it again and it fails to open every time.
I even tried re-downloading KSP and that file also fails in the same manner. And that copy has no mods in it. Does anyone here know what I can to do get KSP working again?
