Hey, I'm in the quest where I'm supposed to retrieve the three books in the Gnisis Temple. I taunted the ordinator next to Vivec's Mask, killed him, and took the books from the bookshelf, but when I return to the vampire and he asks me if I've retrieved the books, I say yes and instead of finishing the quest I get stuck in a loop--he keeps asking me for the books again and again and again, no matter how many times I say yes. is there either a fix or a workaround for this?

Thanks!

Solved! The problem was that I had two copies of "The Old Ways", which was screwing with a script. I dropped one of the books and everything worked fine.
