Good mornin out there My first post but i not my first time in KSP at all. I have the problem, that MechJeb doesn't load properly after launch. The Parts appear in the game and the TechTree, but if i put the MechJeb Pod or the AR202 Case on my Rocket, nothing happens. No Windows Appear neither in VAB nor on the launchpad. After a quick Search in my logfile i found this: Non platform assembly: D:\Steam\SteamApps\common\Kerbal Space Program\Plugins\MechJeb2.dll (this message is harmless) AssemblyLoader: Exception loading 'MechJeb2': System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded. at (wrapper managed-to-native) System.Reflection.Assembly:GetTypes (bool) at System.Reflection.Assembly.GetTypes () [0x00000] in <filename unknown>:0 at AssemblyLoader.LoadAssemblies () [0x00000] in <filename unknown>:0 Additional information about this exception: System.TypeLoadException: Could not load type 'MuMech.FuelNode' from assembly 'MechJeb2, Version=2.0.9.0, Culture=neutral, PublicKeyToken=null'.
