Ahh.... even though the teleporter pro0blem isn't solved, I had one last go and found my way to Serriks tower - and got in. (How come I fought the guard last time? Bah!)
And blow me down, if he doesn't give me the teleporter quest as well. Sigh.
Maybe I'll just go back and see if I' far enough up the list now to progress to the next Chapter ...
I have discovered the cause of my crashes (I think - I can repeat the process that causes the problem, anyway) ... save the current position over the existing save game. It would appear you always have to save to a different filename to the current 'save' being played. Leastways, if I save over the current game, I walk into a crash. Saving over an old saved file seems ok.
