I attempted to turn down the back box lighting on my IM Premium this morning. I turned it way down to 10% to cut down on the reflection on the play filed glass. Once I had it where I liked it I installed it but when I backed out of the a adjustments and started a new game the lighting was back to 100%. It didn't save the lowered adjustment I installed . Any ideas as to why it wouldn't save and how I can get the adjustment to stick?
