stuck with "the unforgiven" quest

[Sturm]

Hi!

I did all the other main quests and now I'm stuck at this. I got Siegfried to support me (can't find Yaewinn nor in the swamps nor at Vivaldi - didn't help him at bank so maybe that's why) and I went to the Narakort inn. I get to fight with Vincent helping me and I go upstairs ...
I get into the conversation and when it ends with Triss teleporting me and Sigfried I get stuck totaly. The whole area is real dark, I use the cat potion but it only lights me up, not to mention I can't move, can't use any of the signs, can only draw my weapons and use inventory and such. There's no map for the location I'm at (maybe it's the quest but I'm not so sure). Basically I can't do thing about it and it's making me angry. Searched everywhere on google if someone else had the same thing happening to him but it seems I'm the only one. It's like the Salamandra base doesn't exist for me :O
I even backed up my saves and installed the game again with patching only to 1.1 (I play 1.3) as some people suggested to others who had bugs but I ended up with same problem.
Any ideas? :|
