MT Enhanced Plugin does not work with updated versions

Hello,

I have the latest version of Trados 2021 and the latest version of the MT Enhanced plugin installed.

I also have a valid API key.

Every time I want to use the Google Translator V2, the error message attached below appears.

I have re-installed the plugin many times, and it still doesn't work.

The SDL Support service told me to make sure I have the latest versions, and I do.

It used to work just fine a few weeks ago, but something happened, and it doesn't work anymore.

All help is very much appreciated.

Thank you!
