Thanks Tim. I'll try reloading Google Earth.

EG

We are simply generating a KML file for Google Earth to display, then handing it over. If Google Earth is then generating an error, all I can do is assure you we haven't changed anything about that file we generate for years.

Thanks for your reply. Regret I count myself as a non-techie so don't really understand what you are saying! The Skydemon app offers the option to view the track of a previous flight uploaded from a mobile device to a desktop PC via the cloud. One option offered is to view this on Google earth. Until recently this worked fine. Now it doesn't...I just get the error shown in my previous post. I don't know whether this is an issue in Skydemon or Google Earth or somewhere else. I downloaded the Skydemon app again but the problem remains. This works perfectly well on my iPad but not on my PC. It's not life threatening but irritating!

When I try to view flight history from the Cloud in Google Earth on my Windows PC I am getting the following message: " Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and attempt to continue. If you click quit the application will close immediately." Whatever I then do it just  throws me back to Skydemon. It used to work fine and I have no problems on my iPad. Any pointers as to where the issue might be? Thanks.
