I recently tried to upgrade to the newest version of CE for windows 7 (non-beta). Halfway through my Antivirus (AVG) started complaining and I accidentally hit quarantine. The computer crashed and when I reboot it, I have no internet access. I can ping google or yahoo, but chrome and other browsers say I have no internet. If I try to uninstall, it says an error occurred and I need to finish a previous setup. If I try the installer again, it says I already have that version of CE installed. Any help would be appreciated!
