Melodyne Editor problem (SOLVED)

I've noticed recently that the horizontal grid lines in Editor 2 have disappeared.  I can't seem to find a way to turn them back on, they've always just been there.  Before I reinstall I'd appreciate any thoughts.  I'll post over at the Melodyne forums as well.
 
Thanks.

The pitch grid settings in the context menu on the pitch ruler? From http://helpcenter.celemony.com/editor2/en/singletrack_tour_42_1.html

 
 

Thanks Scook.  Here's what I think happened:

I had recently changed the contrast and brightness settings of my monitors and I think it made the horizontal lines and shading harder to see.  In my search for a solution, I inadvertently changed the "Pitch Grid | Pitch Background" settings away from the "Keyboard" option so everything looked different. 
 
Christo over at the Melodyne forums suggested I check the "Look" option under the Preferences.  As many times as I've looked at that menu, somehow I missed that option.  By setting the "Look" selection to "Darker" and re-selecting the "Keyboard" option, I'm back in business.

Thanks again!
