I have no mods installed in KSP, and I've uninstalled and reinstalled it 3 times. For some reason, every time I go into the SPH, there are no parts whatsoever. I can load a ship, but if I load one after another, they clip on top of each other. I can launch things that I load. However, right after I uninstall it and reinstall it, I have the parts again! Buuuut when I try to launch a ship, all of the buttons gray out, and I can't move the camera. It doesn't freeze, there are Kerbals in the background moving around. I have done everything I could find, but nothing works. I've installed it and uninstalled it, I've verified the game cache, and I've moved it to a different folder. Please help.
