Samsung Galaxy Tab 8.9 won't lock screen

[AMB_AZ]

My new Samsung Galaxy Tab 8.9 32g won't lock screen. I tried setting a pattern but the configure lock screen still says off. I tried setting a pin and it's still off. When I try to enter the sub menu within the Location and Security menu of Lock Screen it just goes right back to the Settings home screen. This was working fine until I set a Lock Screen background (a picture from my gallery). Please tell me what I'm missing.

Thanks.
