When I open OE 6, all the pre-existing content of my Inbox (including
subfolders and their contents) have disappeared. I can locate inbox.dbx and
the subfolders using Windows Explorer, but I cannot import them into OE 6 or
into Outlook.

I suspect OE collided with McAfee and got corrupted. Is there a place to
download and install just OE 6?

Has anyone else experienced this issue?

I've copied the .dbx file to another computer and tried to import with no
success.
