When I save a project from Trados Studio to the Language Cloud I can initially access the project in the Cloud and make changes in the Online Editor. However, if I then go back to Trados Studio I get an error message "Object reference not set to an instance of an object". although it allows me to continue working on the project. But if I try to go back to Trados Online Editor again I get an error message "Unexpected Error Loading content in server".  The page will not load and it just states "there are no segments to show". So I can't access Trados Online Editor. Why it is not syncing properly and what is the fix? Many thanks
