relicense my ccsv5 because of the computer Mac have changed

Dear Ti

I have a license file for CCSV5 before, but some days ago, my computer have broken down ,and I changed the computer main board.

and when I open the ccsv5 and the CCSV5 is unlicensed. How can I deal with this?

my old PC MAC address is  :D4.85.64.16.95.F2   00.1B.21.54.16.FE

my new PC MAC address is:98-4B-E1-8C-9D-CE   4C-0F-6E-30-F1-EA

The last time which I deal with the licese information:

Activation ID /  Host IDs  

 Primary: D4.85.64.16.95.F2
Not Used

Remote: 00.1B.21.54.16.FE

Entitlement ID: 842A-3350-25A3-11E0-8007-E05B-7799-3786
