seen database destroyed - how to recover?

[Prentice Bisbal]

My seen database got corrupted, so I deleted it, based on what I'd read 
on other posts. In the past this worked (I'm only testing a prototype 
system). Today, I did that, and now I can't see ANY of the messages in 
my INBOX, or several other mail folders. I know the messages are still 
in /var/spool/imap.

Why can't I see them at all? Is there any way to fix this?

I've also been getting ominous errors in my log files related to this:
