I'm having a similar problem as daawgees. Extracted hyperedit to the KSP folder. A Kerbaltek folder appears in the gamedata folder. Run KSP and alt + h doesn't bring up the hyperedit menu. I've manually added the kerbaltek folder to gamedata and no luck. I've started new flights and new campaigns and still no luck. After reverifying the KSP local files, the hyperedit menu still won't appear. The only error I'm receiving in the log is [ERR 18:08:42.811] AssemblyLoader: Exception loading 'EngineerToolbar': 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 'EngineerToolbar.EngineerToolbar' from assembly 'EngineerToolbar, Version=1.0.0.1, Culture=neutral, PublicKeyToken=null'. I removed parts of the Toolbar that Kerbal Alarm runs with thinking it might interfere, and I think that is where the above error is coming from. Weirdly, the flags included with the hyperedit folder are included in the VAB and I can use them just fine. I'm pretty stumped as to why its not working.
