Hello @anitamatthews2609,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having with your account. Your issue seems to describe a reencryption error. Our records show the Master Password of your account was changed recently, please revert the Master Password change and verify if the items in your vault return to normal. Then proceed to change the Master Password again.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
