This is saying that you have a token that has been seen in more ham  
than the total number of ham you have trained (which is impossible,  
so is really saying that there is a problem with the database).

You can export the database to CSV (with sb_dbexpimp.py), manually  
correct the counts, and then convert back, but you're probably better  
off just replacing the database with a fresh one.

(This shouldn't happen again - if it does, the most likely  
explanation is that two processes have the database open for writing  
at the same time, so that would be the first thing to check).
