Authorize.net Add-On API Credentials Stopped Working

Does anyone know if the Authorize.net add-on has stopped working or not compatible anymore? I have the latest version of Gforms installed but the credentials are not green anymore and I have verified the credentials from Authorize.net have not changed. Any feedback would be appreciated!

Authorize.net disabled the account due to lack of payment. I recommend contacting Authorize.Net to resolve the issue. Thank you.
