So, how do I change the thread to answered?

I've done it! It works now with all of my mods. The mod that caused the hassle was the toolbar mod. I don't know why though - I updated it before, and it broke MJ. But if I added each mod one by one it works. Kinda odd, but at least it works now! Here's a list of the mods I use: Toolbar ActiveTextureManagement B9 Kerbal beautification -City lights and clouds Kerbal Engineer redux Ferram KAS KerbalJointReinforcement Kethane Hyperedit Kethane KW MJ2 TacFuelBalancer RealChute VNG parachutes And the Interstellar mod! It's obvious why it took me a good while to pinpoint why my Mj broke, but it was worth it!

I started a new Sandbox and new Career game, both didn't work.

Yeah, but I've removed my mods and now it's there and working.

That worked! After I moved all of my mods except for MJ, Squad and Nasa folders, it worked! I'll add mods in one at a time now and see which one breaks it.

I deleted the MJ folder and reinstalled, but to no avail. And I deleted the .cfg's -- still didn't work. There wasn't any MJ files in the KSP/Plugins folder either. The MJ part appears in both the VAB and the techtree. It still doesn't do anything when I put it on a ship.

Yeah. Nothing there

I'm using the .23.5 version from the spaceport. I did install mechjeb after starting my save, but I did activate the part. I tried it multiple times, with different ships and multiple solar panels, so that can't be the case. Any other suggestions?

So I downloaded Mechjeb, specifically this version: kerbalspaceprogram.com/mechjeb/‎ Everything works fine in career mode, it's integrated with the tech tree, the model is there. But when I actually put it on a ship, it just doesn't work. The grey tab that's supposed to be there isn't. And there's a red light on the part - maybe signifying that it isn't turned on? So does anyone know to make it work? Is there something I'm not doing or something I'm missing? Thanks

C'mon! I want my R.A.P.I.E.R engine for Minmus endeavors!
