Hello @bec,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issue you are having with your account. How did you transfer the items? Norton is not on the list of sources for Import, if you need to import them you would need to use our generic CSV file. Please verify that the items stored in LastPass have all the required information (URL, username and password) in order to work properly.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
