Depending on when and where you downloaded 1.04, you might have had problems with it locking up during the registry scan. There's a "new" one available from the Majorgeeks site as of about 10:30 EDT last night which clears up nearly all the problems everyone was having with 1.04.
Considering there's no change in the version/build designation, I suspect the original file somehow got corrupted during or after it was uploaded to the servers, and got replaced with a fresh copy.
