I've been having a problem with mechjeb in .23.5. I been able to install it properly i think just dragged the file from the .rar to the game-data and when i load it and put the modual on a ship the tab appears but nothing is on the tab. ive disabled my anti-virus and tried the latest versions but with the latest versions the tab doesn't even appear. maybe its a mod conflict but not sure where to find that. pic should be below if anyone can help it would be very appreciated. Thanks This game below is a newly created sandbox same thing happens when launching as well.
