Seems everytime I start a new game a different quest breaks. Last time it was the door to the underdark in the Raven Monastery, this time it's the dark trents in the Fell Wood. HELP!

I'd try uninstalling and re-installing the game. If you're on Vista or Win7, run as admin when installing, and install outside Program files.

Thanks, I'll try that. Truely a frustrating experience.

Tried that and it seems that it's stuck on the evil treant quest. Gone through the game probably 10 or 11 times now trying different things and quest is still broken.
