"Contacts" Error Message

Having trouble with my contacts. Many duplicates. And I get the following error message on start-up. Any suggestions? Thanks.

[Google Contacts]Uploading item(s) to folder ‘*****@gmail.com/Contacts’ failed due to the following error: Quota exceeded for quota metric ‘Critical read requests’ and limit ‘Critical read requests per minute per user’ of service ‘people.googleapis.com’ for consumer ‘project_number:920743529221’.

I know this error happened sometime ago with some older versions of eM Client. Check you have the most recent version via the webpage below.

Note:- Before doing any upgrade, make a backup via “Menu / Backup” or “Menu / File / Backup” (for older versions).

Thanks for your reply. I am running 8.2 - the latest version. And it seems to be running better today. I still have a number of duplicate contacts, however I’m not getting error messages. I’ll continue to monitor. Thanks again.
