Please help using Dev. Environment mode

[Chronogyros]

Hello all. Brand new to the forum, but have been viewing threads for a few days now. Additionally, this is my first attempt at a custom story. I've been doing well so far, finding help in the forums or via tutorial videos, but I seem to have finally hit an unsolvable (at least for me) rut.

In finally activating the Development Environment, instead of loading the game over and over again, I have come in contact with a few issues.

Once I load my map:

1) When I press F1 to activate debug mode, nothing happens.
2) When I press F5 to reload, again nothing happens.

I'm pretty sure I followed the tutorial on setting this up perfectly, so I'm not quite sure why it doesn't work. Any help on this would be much appreciated.
