I don't know if I have posted this in the right section. I'm a newbie web designer and I was so worried when after trying for several times, I can't access any website using my PC. There's internet connection because I was able to open Yahoo Messenger. But when I type a web address, firefox said "Not Authorized". Explorer also failed to open any website. I'm so worried I might have clicked on something while toying around with the control panel. I am a designer and not a computer expert. I hope you guys can help me. Thanks in advance.
