Thanks!
Yes, I have found both doors leading too/ from the sewers, earlier today.
I have downloaded the patch, but when I go to install it, it states that it is not a valid Win32 application.
I think that the problem with Assassins Guild came from the black screen I got, but I've seen in other posts that others have had the same problem with the Thieves Guild door. (One that I really want to get past, as I only need the Holy Dagger to have all 3 sacrificial items)
These wouldn't be quite as important matters to bypass usually, but I am trying to finish off all the quests in this section, before I move on to the Wasteland (I only have 1 council member left to get) <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
