chrix I've tested it multiple times, as i said it's either incompatible with other mods, PC issues or you don't know how to install it. For case 3 a little tutorial:
Unzip the compressed file, take the file inside out.
Then go to your cosmoteer trajectory and go to mods, put it there.
Then go to the mod's screen (in game) and turn it on, then restart your game and.
It should be running now.
