i HAVE COMPLETED DAVENTRY QUEST BUT STOPPED DEAD IN MY TRACK WHEN I GO THROUGH THE WINDOW TO THE 2ND QUEST BY THE BLACK BEAR?

Black bear??? You must mean the shadow creature that pushes you back through the green portal you just came in... Just go ask the sorcerer by the lake in Daventry (the guy that is half flesh and half stone). He will tell you what you need to do to. If you need to know more, just ask, I'll try to reply as soon as time allows me to.
