Hey, I realise I'm likely to bring down the wrath of the forum with this one, but try as I might, I cannot get MechJeb (from fresh today downloaded MechJeb2-2.3.1.0.zip) to work with my up-to-date KSP v0.2.24.2.559. From the forum lead-in post I assume that 2.3.1.0 should work with my KSP version. I'm putting the entire zip contents into the main GameData folder (replacing previous MechJeb version which worked fine with whichever older KSP version I last played on). I've started new sandbox modes, as well as continuing saved games, and despite having the AR202 computer in the parts window, I do not get any 'Mechjeb' button or an of the standard windows. What am I doing wrong? (I've tried both x64 and 'old' versions) Cheers for any help ProjectLefteye
