Unfortunately, they're all the same error, ending with:

    File "e:\src\spambayes\spambayes\classifier.py",
         line 217, in chi2_spamprob
    File "e:\src\spambayes\spambayes\classifier.py",
        line 465, in _getclues
    File "e:\src\spambayes\spambayes\classifier.py",
        line 316, in probability
    exceptions.AssertionError:

This is a sure sign that your training database has become corrupted, and
you have to retrain from scratch.  If you saved your training data, that's
easy:

    SpamBayes -> SpamBayes Manager -> Training ->
        check the "Rebuild entire database" box,
        select your training folders,
        click the "Start Training" button

It's very unusual to get a report of database corruption under the Outlook
addin, and I don't have a theory for why it happened.
