BlackExcalibur

I've already talked to her about that quest before and talking to her again doesn't seem to change anything.

So I'm at the end of the game and I'm trying to use the teleporter to get into Hawthorne's castle but it isn't working. I have all five brooches, the royal seal, and I've talked with Khoth and Aydin but Erika doesn't show up and teleport me when I get to teleporter. I've tried talking to Erika but nothing seems to be working. Does anyone know what I'm missing?
