Is the backlight option greyed out on both your cameras? If it is, check to make sure the option is actually supported by your camera model, as I think it s fairly common to use one generic software suite for simiar cameras which may not share all the same features. Check on Micro's website, the FAQs page might be able to fix your problem.
