vahtacen problem

[abercrombie]

Hi,

I'm stalled on the Vahtacen quest.

When I first got to Vahtacen Lorsel I triggered the pressure plate to open the doors, I then ran away and did something else 'cause I found the wriaths too tough at the time.

Now going back the pressure plate won't trigger and the door remains shut.

Any ideas anyone?
