lonewolf--Well, I goofed. It is the UserName.wa~ file you want. If you have not already removed the corrupt UserName.wab file from C:\Documents and Settings\UserName\Application Data\Microsoft\Address Book folder do so. Now you should still have a UserName.wa~ file in that same folder. Rename it to UserName.wab. Your Address Book should be restored. (Do not forget to open the left panel options to see your contacts.)
