Ok the problem begin when i begin using fiddler it was really usefull for facebook games, etc. But one day when I started the computer the internet conection was not working, so after many tries i I opened internet "Tools" and then "Internet Options" then "Connections" and finally "LAN Settings
there in "LAN Settings" I disabled "Use a proxy server for your LAN..." i accepted and i get out. The internet was working again but fiddler was not.
I already tried restarting the computer, reinstalling fiddler and using internet as an administrator changing the proxy server notes: I have IE 9 I use fiddler version 126.96.36.199
