Instead of messing around with utilities that "undelete" files, you have the .dbx files, well done! So get the files to the computer in question, email them or bring/send the CD, and Import them into Outlook Express. Just go to File, Import, Messages, choose the version they came from, locate the files and choose "All" messages. You will have a lot of old messages you don't want, but get rid of all the unwanted old messages and finally move the folder you lost to an appropriate place in Outlook Express. It's fairly simple, there's an Import Wizard in Outlook Express too, if you get confused.
