Hi, I've mentioned this in another thread but are you using the Clarity setting at all? Setting it to anything other than '0' results in the 'Storing' issue. Not sure why this is but hopefully it's something that can be fixed in a firmware update.
You can't use the front/rear dial to control aperture on a lens with an aperture ring. However, what you can do is control shutter speed which then will affect your aperture. To do this, set your camera to program mode with aperture, shutter speed, and ISO on Auto.
