Question on importing data

Before I reinstall windows, I exported all data from Notes Client. And then import them after reinstalling. However, I find there’s something wrong with the AddressBook. Whenever I open the detail contact info of a person, a dialog show up and ask me to connect to a LAN server. Adding new contact records is OK, just can’t edit old ones. And all parts of Notes work properly except this one.

I tried to add new contact records, export them, delete them and then import them again. They become unavailable either. So, I think this is the problem of Notes. What can I do to get my data back. I don’t want to type them again. There’re too many records.
