I took a look into your account, but do not see that you have an event currently active in your account. I did see that you had an email scheduled for tomorrow (March 7th). In order to made edits to a scheduled email, you need to unschedule it. You can do this by selecting the Actions button acoss from the scheduled email, and select the Unschedule option. After you select Unschedule, you can go to edit the email and make any changes you need to make, before you schedule the email again!
