okay, I've had this problem a while now.
I'm using unity 4.7.2, (yes, it is old. It's the only unity program that I have got working).
When I put in part tools as a component on the normal game object, and hit "set GameData Directory" it doesn't do anything, and pops up this in the console:
MissingMethodException: Method not found: 'UnityEditor.EditorWindow.set_titleContent'.
KSPPartTools.PartToolsInspector.OnInspectorGUI ()
PartToolsEditor.OnInspectorGUI () (at Assets/PartTools_KSP11_2/PartTools/Editor/PartToolsEditor.cs:18)
UnityEditor.InspectorWindow.DrawEditor (UnityEditor.Editor editor, Int32 editorIndex, Boolean forceDirty, System.Boolean& showImportedObjectBarNext, UnityEngine.Rect& importedObjectBarRect, Boolean eyeDropperDirty) (at C:/buildslave/unity/build/Editor/Mono/Inspector/InspectorWindow.cs:1094)
UnityEditor.DockArea:OnGUI()
It usually pops up a file directory window, that isn't happening.
I obviously don't know what I'm doing. People whom do know please help.
If anything a workaround would also be great.
