So I've been trying to set up parental controls on an account. Now when I go to parental controls, I click an account and it says that it is unable to make changes to parental control settings, and contact System Adminstrator. It was working fine before, and only started recently. I tried making new accounts or placing restrictions on another account, the error still pops up. My system is 32 bit. What can I do to make it work again?
