Just redownloaded the installer ( originally just downloaded the .24 game ). Still had to change folder name from "mechjeb2-2" to "mechjeb2" to stop error on loading. Mechjeb is showing up on tech tree, have to unlock it to test. edit****** ok tested, its working. But a bug surfaced. When using toolbar mod by blizzy, modules for mj show up as "viewable buttons" when they havent been unlocked on the tech tree yet. For example, accent control shows up. But wont do anything because the tech isnt unlocked. It wont control throttle, it will steer, and set maneuver nodes but wont excecute. keep that in mind if anyone is wondering why things arent working. if you click on the mj tab ( usually docked on the right of the screen) you will see the actual unlocked modules for your given tech tree location.
