I am trying to install MechJeb 2.5.5.0 on Windows 7. Tried the straight install, then again with CKAN. Not sure if I'm doing something wrong, but I see no windows for MechJeb when I start. Tried a clean installation, still same deal. No other mods running. Any help would be much appreciated. Thanks!!

Nevermind. I didn't realize you had to add the controller to your rocket for this to work.

Update: it still doesn't work at all when I put it on my D: drive instead of the C:, but it's a small game, I can deal with it on the C drive for now.
