Hi, I bought Asus laptop last few days and got 2 bundled license keys of Bitdefender Internet Security 2013 from the seller. Each of the keys are valid for 6 months, thus 1 year in total. I was told that there should be no problem if I register both key at the same time as the validity days will be accumulated. I added 2 keys when my trial period is still valid so I expect the total validity days to be 365 + 30 days, but Bitdefender shows me only 6 months. Please help!
