SketchUp Connection to Internet

Good Day All
I have just had to reinstall SketchUp 2018 Pro after the Windows was corrupted by a power outage.
I initially tried to reinstall in the previous directory " F/Program Files/SketchUp/SketchUp 2018" but the programme kept telling me that their was no internet connection.
I then tried all the advice found on the forum about installing as Administrator and clearing the Chrome Cache all to no avail.
I then uninstalled the programme and reinstalled it on " C/program files/SketchUp/SketchUp 2018" as Administrator.
Once again I keep getting the message “Bummer you are not connected to the internet, try again later when you are connected”.
When I am in SketchUp and I select help it takes me straight to the internet page and I can brows the whole page.
What am I doing wrong. I have set Windows Defender to allow Inbound and Outbound traffic from SketchUp.
Thanks for you assistance.
