Rich,
I used to use that version. Have you called TM and ask about the latest version? Trend Micro seems to just support you and give you free virus definitions forever. I asked them once, and they told me that when my year was up, my new virus definition subscription would be like $14.00. No lie. I must have misunderstood. But, I have had it now for over two years and have never had to pay for a new subscription. But, if you call and ask them something, I bet they will say, "Hey we have a new version for you. Here is the serial key." The name is at the bottom here. I can never remember it.
