I bought Ad-Aware SE Plus edition at Costco, after liking the personal edition. I was able to update the Personal edition, but not the Plus edition. I need to register my purchase, but I don't know how. Registered users download the new build using a download link with username/password supplied in an upgrade notice I don't have or didn't receive. Customer support asks for a password I chose when I registered. Catch 22. I am using version 1.05 Plus (build 1501) and it initially says version 1.06 (build 1610) is available, but then says no updates were found. I will appreciate any help you can give.
