So a thing happened: I install KSPI-E by merging the GameData folder found in the .zip file with the GameData folder found in the KSP folder (the same for tweakscale) and boot up KSP. I load a save just fine, make a craft, save it, etc. But when I try to launch, all buttons become grayed out and I can't do anything. I restart KSP and try to load my craft. The Load button looks as if pressed, but nothing happens. Halp meh! (Note: on different computer than the one I have KSP on, no logs as a result) I really do want to play the game with this mod, but I can't, it seems. Hallelp ples
