I am having an issue exporting the track into an mp3. I am prompted with an error message about the email not sending. i break everything so I am sure I messed something up.
The message would suggest you are using File, Export, Send project as an email. for mp3 and your email program cannot be found ie you are using Webmail rather than a dedicated email program such as Outlook.
Try using File, Export, Audio as mp3 (Shift M), and if you are wanting to send the output by email attach the mp3 in your mail program or webmail.
