Although I can access the settings as shown below, I can't change them. And I don't know how to change them as well. http://i.imgur.com/YGw9MdQ.png http://i.imgur.com/5zH2edv.png If I try to change any of the settings, I will get an error similar to this below. http://i.imgur.com/idb6Cf4.png Any advise? -- Yours sincerely, Singapore Citizen Mr. Teo En Ming (Zhang Enming)
