title: why won't Blender. files convert to FBX files in Unity 5.0
body: <p>After  Putting a model in unity from Blender it sais:</p>
  
  <p>Blender could not convert the .blend file to FBX file.
  You need to use Blender 2.45-2.49 or 2.58 and later versions for direct Blender import to work.</p>
  
  <p>Note that i have Blender 2.71
      UnityEditorInternal.InternalEditorUtility:ProjectWindowDrag(HierarchyProperty, Boolean)
      UnityEditor.DockArea:OnGUI()</p>
