Recover corrupted data: Windows Address book

[mvAnalyst]

How to recover data in WAB file that gives msg: "the specified file does not seem to be a valid Address Book file" in W98SE. Backup of file has same problem. The program works OK on empty or newly created WAB file.

Running AVG antivirus and Tiny firewall. Could I have let something in that messed with that file?

Reinstalled W98 and W98SE Updates - no change.
Tried to import into IncrediMail - failed!
changed corresponding WA~ file to WAB - same result.

Help! And thank you.

to update -- found solution:
had re-installed W98se, but had not re-installed Outlook Express, or had installed it but had set windows update personal settings to exclude OE.
x.WAB written by oe6 WAB.exe not readable by oe5 WAB.exe.
Solution was to update OE to OE6. That also updates WAB.exe.
