There seem
    to be silk-screen artifacts way out of the board outline (720 
inches in
    the Y) and the drill file has all of the drills clustered around 
the
    origin.  I've posted a zip of a few Gerber layers and my PCB 
file if
    someone has a moment to verify what I'm seeing.
What version of pcb are you using? What gerber options?
I can confirm that your gerber files are messed up, but
I cannot reproduce with the 2010-Sept release, or in the
latest source from this morning.
