Evaluation license expired

Hi, 

My evaluation license has expired a couple of days ago (Cloud security).

Now I have purchased 400 user license and want to activate the license to my existing portal as we already did AD synchronization. How can I get my user name enabled to activate license. Request you to suggest.

I am unable to login into my websense web portal to activate the license.

PIN Number is: 343701.

Thanks in advance.

Thanks and regards,

Ashok Kumar S.
