Wot? No LM descent engine?

[heatshield]

Stumbled on the totally awesome Orbiter few weeks ago, all hail Dr.Schweiger - I can get to the moon ok but cant
light the LM descent engine in either my NASSP5 or 6.4.0 - I've gone thru the checklist but only seem able to get the
LM RCS lit... Is this a known issue, or a little switch hidden somewhere not mentioned???
Does the AGC have to be kicked in?
Should I give up and try downloading the 6.4.2 release?

thanks in advance

Here is a checklist (follow in order):

Panel One:
Descent He (2 switches) - Close
ENG ARM - ARM

Panel Eight:
Master Arm - ARM
DES VENT-FREE
He Press DES START - FREE

Panel Three:

ENG GMBL - ENABLE

The LEM is configured with it's main engine listed as a hover engine, so you have to use the zero on the numpad to turn it on.
