It's not working for me. The modding tools launcher won't launch, and CTRL E doesn't do anything on regular single player launcher. I verified the integrity of both on steam, and apparently one file needed to be reaquired. And yup, both files are on the same disk.
Just tried restarting the pc. With the mod launcher I only get to the game launcher. If I hit Ctrl E there, nothing happens. If I hit play single player, it just turns off after a second or two.
