Stuck near end, game will not progress [Possible Spoilers]

[HopkinsProg]

I am having an issue, where the game seems to be stuck and I cannot go forward. I have the Steam version of the game.

I am in the Chancel, pretty much at the end. I have the orb and the tar placed on the pedestal (orb is whole and not glowing) and the gears have been jammed/broken. However, despite these actions, the electric/magic field is still in place and not being absorbed by the orb. I cannot reach the door to the Inner Sanctum.

I really hate getting this far and then not being able to finish. I don't believe I've missed anything. Maybe someone with more knowledge than I can help me get past this point.

Thanks!
