The tutorial says to select the "Vault108a" in the list of cells. However, my Cell view window does not give me anything to choose from under the "Interiors" drop down box.
Yeah, I went back after a small break, and re-read the tutorial and caught it. Sorry for wasting your time. I'll slowdown and start paying attention to what I'm reading.
Thanks for your help
Did you load the Fallout3.esm? That is the first step.
