Hey all, I'm posting this one because I'm really out of ideas right now. When I try to access Windows Firewall in the control panel, I hear the "click" sound from windows, but nothing happens. I've checked and the service is running normally, I restarted it and still nothing. When I try WF.MSC, I get an error "there was an error opening the windows firewall...." Everything related to Windows Firewall doesn't open, like clicking directly on "add an exception to Windows Firewall", I click it and nothing. No error message. I'm currently running 64 bit Windows 7, let me know if you have any suggestions please. It's noteworthy that from a few weeks back my internet has been acting up, only now I realized this problem with Windows Firewall, I don't know if it's related. Thanks!!
