PCB Designer Help for newbie / PADS user

Hi, Everybody:

                      Well, this is embarrasing, but I cant get anything but a blank screen.

I am using a brand new installation of PCB designer 16.6, and loading fulladd.brd from the tutorial, but I don't see anything at all on the screen. I have fooled around with every color or visibility dialog I can find, but no luck. I must have the display turned off in some way, I just can't find it. I get the same results when I try to inport a PADS ASCII as well, it says import was successful, but I don't see anything.

Any ideas what I might be doing wrong?

Thanks!
