No idea if anyone else is having this problem, or if there's a solution anywhere, I have installed MechJeb correctly, the part shows up in the editor, I put the part on my ship and I get none of the MechJeb windows or anything. I go to launch site there is still no MechJeb windows, it is not working at all, I looked on the internet and I couldn't find any solutions Image shows mechjeb on ship without any mechjeb windows. UPDATE: I found solution, turns out one of my mods (HyperEdit or Chatterer, don't know which one) was causing it to not work.
