Getting to get 1Password3 backup data into 1Password4

Hi there,

Last week, my hard drive died on my Mac mini and, to make matters worse, the Apple Authorized Repair place killed my backup drive. Fortunately, the place did copy most of my data (sans Library and Applications folders), but that has only left me with backups of my 1Password database. I downloaded 1Password4 from the App Store, but it won't let me do a restore. When I do, I get this message after I click on "Show Files." The dialog appears in Finder. Any help would be appreciated.
