If you have recently installed/updated Avast and it is not allowing you to send emails from SportLogic, it could be because of their security settings.

Please refer the Avast document below to disable their mail shield

If you are still unable to email after following the above-mentioned steps and are using the Avast Pro version, turn off Anti Spam filter and try again.
