Hi adaware1,
Which Build of Ad-Aware did you purchase? Since you are looking for an upgrade, I assume that it was not SE 1.06r1 ?

Select "User Information > License Info" - check to see whether your license has expired or not. If not, select "Resources > Product Downlods" and click on the link that applies to your license.
If it has expired, select "Customer E-Store > Renewal Instructions" and follow the prompts.
To download the (free) Personal version, go:
