Hi, yeah, that's weird all right. Sorry you are having these problems.
Can you post a screen shot of the browser expanded? Is there some way that everything is there, but invisible?
Also, if you create a new design, and add primitives, do you see anything?
Did you get any warnings about your graphics card when you invoked Fusion? What kind of computer are you using, and what are its graphics capabilities?
Finally (and I think this is a desperate shot in the dark, just try the "fit" command (bottom of the screen):

just on the off chance that the stuff is there, but not in the view...
Thanks for your patience.
