How to enable Mission Editor in TGE

Hi All,

I've searched everywhere with no results.

I'm doing a modding project for school and wanted to mod Edward F. Maurina's Maze Runner Advanced that ships with his book GPGT.

Unfortunately this final version of the game has the Mission Editor disabled. i.e. when I press F11 in the game it tells me the Editors have been disabled instead of the world editor opening up.

Does anybody know how to remap this key to open up the generic Mission Editor.

I can't find Maurina's e-mail anywhere. I suspect he doesn't want questions like this anyways.

Thank you for your help.
