no i dont, is that something thats needeed? I just downloaded the 4.1.3 version, installed, and still no success

I cant get it to work on the latest 1.9.x verison either, i literally copy the latest 2.9.2 mech jeb version into game data, but nothing loads in game. No error message either. This is with a fresh install ( no mods or addons ) of the latest KSP.
