Bdis 2012 Product Key Not Working With Bdis 2013

Hi, I have purchase 2 BD Internet security (2012) 3PC solution last year but use only one because of some reasons. Now i want to use my other product key as my subscription is expiring soon. but when i entered my other 2012 BDIS key in BDIS 2013 it give me an error, that "We were not able to validate the license key you entered. Please try again, or you can contact Customer Support to get help with this issue."


Please solve my problem as soon as possible as my licence is expiring in 9 days.
