I used to buy BDIS from Flipkart's WS Retail, I think the company that sold BD products in India was 'Unistal USE Group' in New Delhi. Lately my friends who have bought BDIS 2012 faced unsolvable problem regarding "invalid key"- Bitdefender apparently told that they couldn't do anything and contact local Support. Which turned out in a refund. Now I do not want to buy BDIS 2013 because of the firewall's kid treatment of 'Paranoid Mode', can I use the new BDIS 2013 key if I buy one from flipkart.com and use it in renewal of my existing BDIS 2012?
And why have BD disallowed BDIS 2012 keys from Unistal group? It is really confusing and frustrating for the users.
