Renewing License on Symantec Endpoint Protection version 11.0.

I just paid for the renewal of our company's Symantec Endpoint Protection.  We have version 11.0.5002.333.  I am confused as to whether I need to do anything with the zip file Symantec sent me to renew or if anything has to be done other than the online purchase of the renewal.  I have searched and have seen mixed info on what I need to do to finish the license renewal.  Looking for help on this.

Thanks.
