Hi, I'm running KSP 0.90.0.705 Beta and I tried to install Mechjeb2. I downloaded it from curse: http://www.curse.com/ksp-mods/kerbal/220221-mechjeb#t1:description and extracted the files from the zip into the gamedata. Nothing happens in game and there are no extra parts in the builder. What am i doing wrong? Thanks - - - Updated - - - Im playing in sandbox btw
