Portal Issue in Chateau Irenicus, Can't go to second level after returning from IWD Options

[discordia]

From Larrel I went to Dorns Deep, there I ran around for as long as I could -my advances were definitely hindered by those immortal snow trolls- and from there I took the land route to Kuldahar to take the portal. There was a mysterious sequence involving 4 elves, at least I think they're elves and I find myself back at Candlekeep, where I went straight downstairs, talked to Gorion and Hrothgar. Then it's back to CI, where I still can't use the portal.
I assume it's some sort of Global Variable not having been set...still, would be glad for any assistance as I'd love to keep adventuring and I fear MoveToArea would break the quest chain.

Oh yeah, I should mention that I'm running a rather big install of BWP, none of the BG2 megamods though. I can of course post the Weidu log. There might have been some complication because the zone I was transported back to, I hadn't explored yet, so when I left that place after the portal wouldn't work and went back there I was greeted by couple of Duergar.

And yes, I posted a similar thread on SHS, in their megamod section, but from the lack of response I can only surmise they never encountered such a problem.

Okay...spoiler tags don't seem to work for me, so I'll link to my Weidu log.

I don't know any mod you installed. Key you need is in the chest in Ellisime'room. This is original game plot not NEJ.

Maybe a Variable or Cluaing in a key?

misc4G I believe

Ha, that actually did the trick. I plundered everything the first time around, and it wasn't in that room either, but cheating it in enabled me to pass on.

Thanks a lot.
