I'm trying to install roster gallery for the first time version 2.6 and this is the error I receive when I hit go on the installer

installDb: 1101: BLOB/TEXT column 'disc' can't have a default value -( CREATE TABLE `roster_addon_screenshots` ( `id` int(11) NOT NULL auto_increment, `file` varchar(255) NOT NULL default '', `caption` varchar(255) NOT NULL default '', `disc` text NOT NULL default '', `ext` varchar(255) NOT NULL default '', `catagory` varchar(255) NOT NULL default '', `approve` varchar(3) NOT NULL default '', `votes` varchar(10) NOT NULL default '', `rateing` varchar(10) NOT NULL default '', PRIMARY KEY (`id`) ) )

any idea to what I can do to fix this as I don't see any refrence to it already in the tables of the database.

odd issue.. redownload the package remove any lines in the roster_conf that as addon_rg in config_type remove the roster_addon_screenshots table in mysql and the screenshoots folder in the base roster dir and try installing agian
