Hello! I only made a name on here because I knew I would get a knowledgable answer. Recently, I had to do a system recovery of my Compaq computer. Everything was reset, obviously, and I have been redownloading and reupdating everything. I have McAfeeAntiVirus 2010. Before the recovery, I had downloaded it using the card and everything was all wonderful. I was just wondering, can I re-download my McAfee since I have made an account on the McAfee site and have the data on the card, or do I have to buy another edition and another card? Thanks!!
