Hello @AngelaM7685. I'm so sorry that you experienced these issues with the renewal banner and your campaign not saving. When you were attempting to save your email, did you see any errors appear? Also, did the saved draft ever show up under your Campaigns? If you sent a test email to yourself, you can use this to recreate the email in your account. I understand that is not ideal but you should be able to copy and paste the text that you had put into the test email into this new email.
Whenever you create your next email, if you are still experiencing issues with saving, try using a new browser. There could be a browser issue with the one you usually use. Of course, if you ever need immediate assistance during the week, please contact our Support department at 866-289-2101 Monday through Thursday from 7am-11pm and Friday 7am-9pm.
