Transfer the folder with all the .dbx files to your desktop and try to import them from there, Suzanne. I've heard of a few people, having problems impoting from a zip drive. It's also possible that you didn't export the messages correctly, in which case you might have lost them. If you save the folder with the .dbx files to your "My Documents", for example, you could change the Store Folder (where OE looks for your emails) to that saved folder. To do that go to OE > Tools > Options > Maintenance tab > Store Folder button > Change button and browse to the folder you saved in My Documents. That should import/replace the emails for you.
