Import Joomla 1.0.11 Articles from MYSQL DB to WordPress 3.3.1

Import Articles from Joomla 1.0.11 into WordPress 3.3.1 using Mambo2WordPress Import Wizard. Wizard is installed and connecting to Databases however I get "Query Failed" so there must be some difference in the database table names where the data gets pulled. Both Joomla and Wordpress are installed on the same server, same domain. If you have another tool that will do this, fine, but it CAN NOT destroy the existing Joomla database as the site is still live until the import into wordpress can be completed. ONLY Bid if you are familiar with the older versions of joomla.
