I ran an update on my site from 5.4.1.1 to 5.4.2.1 and I now have a crashed site. The error message is:

PHP Fatal error: Uncaught exception 'ADODB_Exception' with message 'mysql error: [1146: Table 'mac2011.composertypes' doesn't exist] in EXECUTE("select * from ComposerTypes where ctID = '14'")

I ran the update from the dashboard::sitewide settings::update and the error message cam up straight away. I have a backup of the database but I would like to fix this so I can use the latest version. Any help please
