can someone help? just installed the latest RS2. When trying to create the first categorie I got the following message. ...

DB function failed with error number 1146
Table \'castle00_joomla.jos_rsgallery\' doesn\'t exist SQL=SELECT a.*, b.catname AS category,b.catname AS name FROM jos_rsgallery AS a LEFT JOIN jos_rsgallery AS b ON b.id = a.parent ORDER BY parent, ordering

what have I done wrong?

thanks
