Trying and faling to upgrade to version 3

I’m trying to upgrade to V3 and so far I’m in trial mode. When I use your tool to lookup my serial number it gives me one that I believe is associated with V2 and it isn’t accepted. What should I do?

At the top of the Purchase window, there should be a Check Upgrade Options button that will let you get the upgrade discount. You do not need to re-enter your old serial number if it had already been entered into SpamSieve 2. After upgrading, we’ll send you a new serial number for SpamSieve 3.

Thanks. I figured it out.
