I downloaded the free 2007 version today and had trouble checking for updates. I ran the scan anyway and there were no critical issues but 412 privacy issues. I clicked on the privacy tab and removed them. I'm not exactly sure what I did next but I think I tried to check the box on the privacy tab sheet again.
I received the following message and a request to tell Lavasoft about it.
