So i installed my construction set to make a mod, and when i opened it up and went to make a new item, i clicked on the button to choose the mesh. The box popped up, but it said no items matched my search and there was nothing in the box. While in the meshes folder there are hundreds of meshes. I don't know why it's not showing up. I'm playing on windows 7 x64 bit, game runs smooth, and isn't in the program files directory. I've used it before on this computer but not on this install, so i don't know what it is. Any ideaS?
