I just recently went through with a fresh download of KSP .16 (.17 is having too much trouble with me) and decided to try out the Kethane, Payload, and Satelite mods from MMI. I have all the plugins that are "required" but I can't seem to get mechjeb to function properly. I have tried all the different part versions of Mechjeb and they all have the menu except I can't use the auto-ascent function on my rockets, as that is as far as I have gone in trying to find out all the bugs. I have tried building simple 1 fuel, 1 rocket ships that can't even start up, Mech jeb just keeps awaiting launch after the 1st stage is going. Any solutions? Edit: I am using v1.9.2 as far as I know. After some basic toying around I have also found that my rockets will only sputter for a split second (with a mechjeb part) and then stop going all together no matter what I do, I am starting to think that this may be a bug with the PowerTech_MuMech Plugin.
