Sincerely, MartiIssues converting serial number into license keyI purchased Backup Exec 11D and the Domino Agent from CDW. I received an email from Symantec with two certificates, one says EXPRESS at the top and the other says SUPPORT at the top. I tried following the directions for logging into site for doing this conversion, updated my account, this is an upgrade package, and then tried to enter the serial number. I keep getting an error message that says my serial number is invalid. I entered all four serial numbers one at a time from both certificates and get the same result from all four serial numbers. I called CDW for support and they told me to pound sand, call Symantec. What am I doing wrong?
