I've been age verified for over a year and half and just noticed my marketplace setting set on general, and went to click and change it and its not highlighted to let me change it...I don't get how to clear my browser cache like it says, and just don't understand why I have to hassle with this, should just give me that option to change since I've been with sl for over a year age verified...So, what do I do to fix this?
