Ok... I've been goofing around with my game a bit. I've gotten several of the mods to work correctly and I've realized that some mods are dependent upon others. And the 'toolbar 000' thing... and the parts.. and the models... and ... well. Let's just say that I find it all just a little bit confusing. I've gotten all of this stuff to work at one time or another, but as I was toying around with the latest addition to my game, I noticed that the mechjeb had stopped working. It was still there, but the tab had disappeared from my flight display. In my attempt to fix this, I think I broke my game. Now, I have re-installed a vanilla version of my game, and I want to set it up with particular mods (namely: Mechjeb2, Kethane, InternalRobotics, Firespitter, DMagic Orbital Science, BioDomes, and B9... and I believe I need to have Toolbar 1.71??) I was wondering, since there seems to be some requirements for some of the mods.. and some conflicts... Is there a recommended process for setting up your game.. ie, Once you install your game, first you add mechjeb2, then add the firespitter mod, next the B9, next add ... etc, etc... Could I get a little advice, please?
