My Accounts Deleted in Identity Safe

Identity Safe Problem

4 months ago I bought a new laptop  and I installed Norton 360 to new Laptop too. Identity  Safe synchronized my accounts from old computer to new computer.  No problem until here.  After I closed old laptop and I have never opened since  4 months.  I have not done anything, no update, nothing. But I changed my Norton account’s mail address on new computer while old laptop closed. After 4 months I decided to open old  laptop. And old Norton ( not updated during 4 months ) wanted to change my Norton account’s mail address from me and I changed.  Because of that identity safe did not work, and I tried to change identity safe’s account to new mail address for synchronize from new laptop to old laptop. How can be possible , I don't know. My old laptop’s identity safe created a new account just like new laptop accounts ( same mail address same password) and old laptop identity safe  was empty . No accounts. THE WORST OLD LAPTOP SYNCHRONIZED  ( EMPTY, NO ACCOUNTS) TO NEW LAPTOP ( NEW LAPTOP DURING ONLINE) AND ALL MY ACCOUNT DELETED ( EVERYTHING, I THINK SO I HAVE MORE THAN 100 ACCOUNTS).  You may not save my account, no longer, but you should fix this problem on Norton.  You have to do.
