OK -- I am not sure what happened, but, after some screwing around, I pressed the 'reset' button in the ship selection/weapon loadout screens, and bam, my choice of ships returned as did the full selection of weapons.
Weird. I have no idea how they got turned off/disabled/removed as choices.
Oh, and I am playing the voice-acted version, by Blaise Russel -- the one that installed with Turey's installer. I think someone was saying earlier in another thread that they preferred Mackie's voice in the previous version. Without having heard that version, I think that Mackie's voice is perfect for the part -- cynical, annoyed, etc.
Anyhow, as always, this board has been very responsive to (yet another one of) my questions -- so thanks again guys!
