Hello I have a problem with the mechjeb2 mod. When i open the game i can't find the Mechjeb2 pannel control. I install the mod with forge and i verify the version of the mod and the game are in the same version. I put the log with this if you have an issue to resolve the problem.
Thank's you

You don't have ModuleManager installed or you need to use the part.

I have the same problem as the person above but I install manually. I put the mechjeb2 mod folder into the gamedata folder, but I cannot see the panel on the left. I used it before. I can also attach a picture if needed.
