@snixdad 4.002 Look at the comments below.
How do I know if it is actually scanning? The gray bar at the top, below the header, does nothing.
Everyone is having trouble with 3.303. Me too. I'm sure they will fix this excellent software soon.
I couldn't believe how hard it was to find the previous version. Maybe I missed the easy button somewhere. I did find it and I'm mirroring it on my website. You can use my mirror to get 3.302 at http://isurf2.com/adw
I was also having the same problem with the latest version (v3.303) crashing. I'm running Win 7 64bit. I took aniceguy10's advice below and downloaded the older version (v3.302) from AfterDawn, and that one now works flawlessly.
