Olympus PEN E-PL1 aperture help?

On the 'M/Manual' dial everything is very dark. When I click the 'Up' arrow to change aperture (the left and right arrow keys) it changed but there is still the scale with a blinking -3.0 that doesn't change with it. So the picture is always dark and I can't turn it back. How do I change it back? (Resetting didn't work & it's perfectly fine on the A/Aperture dial.) Here's a [crappy phone] picture of what's going on: a href="http://i53.tinypic.com/vi1cwi.jpg" rel="nofollow"http://i53.tinypic.com/vi1cwi.jpg/a
