Your screenshot is too small to read, but make sure you are using the email address associated with your Game Account and password to log-in.
If you continue to have issues, you can contact the CS Team for assistance. (It may take some time, as they are a bit overwhelmed at the moment.) Top of Page – Support – Submit a Request. (Make sure to choose an option for each drop-down menu.)
Good luck.
