Locque,
We're talking about this guy? I remember reading that when I joined the forums. I think its clear at this point that this player should be playing a TB 4-5 Arbitrater with Enforcer Carapace, a pump shotgun and a shock maul. Add on the investigatory skills inherent to that class has and a couple social elite advances and from what you've written I think his play style and your game will finally get along.
I've been debating with myself typing this next part and I just can't seem to let it pass without expressing it. Your allowing the autogunners to fire while engaged in melee combat thus killing his cleric seems suspect to me (the reason I say this is as near as I can tell, you are engaged in melee combat as soon as an enemy wielding a melee weapon comes within three meters of your character or NPCs) so I can see why he was frustrated with that character. As soon as he broke cover with his adept the first time and attacked (fruitlessly) with his sword I think you should have realized that the problem was that this guy wants to be an in your face combatant as well as somewhat socially/intellectually able to assist the party (thus my arbitrater suggestion, cheap toughness increases and decent combat skills).
It may be jarring but I honestly think your best solution would be to switch the adept for an arbitrater and say that the arbitrater was there the whole time (psychic memory blocks suddenly failed releasing the characters' true memories perhaps?).
I do not want to come across as telling you how to run your game or that I think you are a bad GM as that is not the case, but I do think this will be the easiest way to curb the "trouble" that seems to be coming from this one player.
