What I did after the storm was to click on the update I wanted, then click "properties" This will display the URL to the backup file. Type that URL EXACTLY as it is into your web browser and it will prompt you for your Username and Password. (provided you can get to update.eventide.com where you are) Use the UN and PW you registered with and it will download the file. Put it someplace easy like c:, then Open back up the update utility,
Click File -> Update from file and choose the .bam file you downloaded from the website.
Piece of cake.
