Hi,
The upgrade scripts should have added that column. If you navigate to siterrot/Setup/Upgrade.aspx does it say you are up to date?
Can you look in the mp_SchemaScriptHistory table and see if any rows in there have error messages, if so tell me the error. If the error can be resolved then delete the rows from the table that have errors and navigate to siteroot/Setup/Upgrade.aspx again and it should try to re-run the scripts.
If you want to run the scripts manually you can find them under siteroot/Setup/SchemaUpgradeScripts. Afer running them you would have to manually set your version to 2.2.3.3 in the mp_SchemaVersion table.
However its all supposed to be automatic so if errors are happening I would like to know what they are.
Hope it helps,
Joe
