When entering valid credentials into the configuration dialog the error "Client ID/Secret invalid" is displayed!
This happens when the trial period is over and no valid license is activated.
- Open the licensing dialog and check if your license is expired. If it is renew it.
- If your activated license is still valid double check the entered credentials.
- Make extra sure not to copy any space characters at the start or end of your text
- Check if you confused any upper case I and lower case L or 1 characters.
