Cannot call constructor – fatal error

I’m trying to configure Snapshot. I set up the Google project and client stuff… I entered the account id and secret. Then I got this error:

Fatal error: Cannot call constructor in /home/content/72/10812172/html/wp-content/plugins/snapshot/lib/destinations/google-drive/Google/Service/Drive.php on line 72

Please advise. I need this backup to work as soon as possible.

Thanks so much.
