I'm trying to install the Antispam recheck plugin, http://wonderwinds.com/hackblog.php/2005/02/07/antispam_recheck_tool_part3

I've done everything exactly as indicated, and the queries work when executing via MyPhPAdmin, but I get the following error when running b2antispam.php:

MySQL error!

Unknown column 'aspm_checked' in 'field list'(Errno=1054)

Your query:
SELECT aspm_ID, aspm_string, aspm_source, aspm_checked FROM evo_antispam ORDER BY aspm_string ASC
