Mac Version. Where's the Mission Editor? HELP

I tried to ask this question before. somehow it ended up in resourses???

I bought the engine Last March. I downloaded and set it up on my mac. I messed with the demo. I couldn't save the demo, I thought I probably tried to do too much and exceded the limits of the demo engine.

Real Life got in the way.

Now I'm back, reading the documentation, trying to get something accomplished that I can look at and say, okay, I can do this...

But I can't find a way to turn on the mission editor.

I can turn on the show tool pro and the constructor, but when I hit F11 in either everything vanishes and nothing takes its place.

I did talk to "Knight" on Minions of Mirth, and he was very helpful. He convinced me that I hadn't completely lost my mind and gave me a few hints, and I guess he actually has gotten something done with his copy of this. (I still owe him-)

But, aside from the mini/limited thing inside the demo, where the bleep is the executable (mac version) mission editor?

Thanks,
