I installed the component & module and went through setup instructions but when I run rebuild list i just get:

Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource in /home/expose/public_html/administrator/components/com_rafcloud/plugins/rc_joomla_content_plugin.php on line 24

appearing several times and no tags generated..

I am using Raf Cloud v. 3.0_beta_9, have checked and re-checked settings etc, re-read instructions but no joy. Am I missing something here? Have tried it on 2 different Joomla installs but both have exactly the same issue. PHP version is 5.2.11

Any help would be appreciated!
