Can't Connect

[Bonez]

I've looked all over these forums and done everything it has said, and everytime I try to open the Auto Updater, it says can't connect, please check your proxy settings and try again. I have tried re-downloading it 100 times, disabled all firewalls, reset my router, I added that line to the hosts file, nothing works. I reformated my computer about 2 weeks ago, and I used ProfitUI before then, and everything worked fine, but since I reformatted it will not work, any help would be greatly appreciated. Thanks
