[RESOLVED] Black screen on running GameEx

I just downloaded and registered GameEx, installed it, setup Mame, ran it, and the screen goes black.  I can get out by hitting ESC but otherwise nothing seems to be happening.  I've attached my GameEx.ini file to this post.

I have Windows 7 64-bit, not running much else on the machine.

Thanks for any help that you can give me.
