My current problem is that when I open the Level Editor, it is just a black box that does nothing and can only be closed by ending the process through task manager. I have updated my Java to the latest version.
I did a re-install of everything, and I used your LevelEditor.cfg again in my HPL2 folder, but it still isn't creating the new MainEditorSettings.cfg for me.
the Map Viewer works fine, so I don't know whats going on!
