I had a similar problem with CFP on one of my many installs. I could not get my LAN to communicate the only way i could solve it was to uninstall CFP in safe mode run the uninstall script this links straight to the download for the uninstall script and/or see the detailed instructions for uninstall here
see the instructions at the bottom titled “For novice users or people that want to save time”
Hope this helps
