As a LAST resort, I downloaded the core file from the webpage and used that but I have yet to figure out what I was doing wrong about downloading the regular way. Think I will try again in a week or so, right now I am TOO FRUSTRATED....thanks anyway!
Bought Ad-Aware Plus (2007) in April of this year (2008), loaded it without a problem, updated the definitions, and then haven't updated it since! (I don't always use this computer). Now I have tried, and tried to download new definitions and yes, I have RTFB, but this basic step now seems beyond me. What in the world could I be doing??????
