Hello everyone, I have a question. Right now I have over 2 months left before I have to renew (which I will, very happy with BitDefender) on my current system which uses Windows Media Center Edition 32bit. In 2 days I will be building a new system upgrading some major components including a new motherboard which supports up to 16 gig's of memory. I will be switching over to Windows XP Professional 64bit to take advantage of memory upgrades (Windows 32bit only supports 4gigs max). So my question is will I have to buy a whole new key for BitDefender for my new system or will I be able to just download the 64bit version using my existing key, which I will renew in 2 months anyway. I was thinking of submitting a support ticket, or just trying a trial version first but I figured to post to see if anyone has had any experience with upgrades. Thanks!
