I uninstalled before downloading the new one. One thing you have to watch for is the update mirror site:
On the update page notice 3 icons across the top. The one in the middle is the mirror location. The default is German, so click 'search for updates' and the location icon will come alive, click the arrow for the drop-down on the right, and you will see "Rootboxen USA," left click it, and then when it shows, right click it and set it as your permanent download site. Otherwise you will get "checksum error" when you try to download.
Also, on the immunize page (click immunize)
there are two items at the bottom. Make sure they read:
--a check box "enable permanent blocking..."
--and a drop box space--choose "block all bad pages silently"
Other than that, keep it in default mode unless you want to run advanced, and then put it back in default when that finishes, and it will run smooth.
