If you run one of the VMS tools and you get no data this 99.9% of the time caused by your API key not working.
API Keys expire after so many days of none use (at the time of writing this article it was 30 but this can change at any time).
The first thing you need to do to check / fix this is log into https://console.google.developers.com and then follow the steps in this video to create a new project / api key. If this does not work (and we have verified that the software is working for us and others) then this issue is beyond the scope of our support and you would have to go to google / YouTube support for them to help with their api key issue.
PS Please DO NOT use the API keys in this video (they have already been disabled as they were only for testing purposes)
