Try:

CREATE TABLE `tmnt_announcements` (
 `id` int(11) NOT NULL auto_increment,
 `title` varchar(50) NOT NULL default '',
 `announcement` text NOT NULL,
 `userid` int(10) NOT NULL,
 `time` int(10) NOT NULL,
 `ip` varchar(50) NOT NULL,
 `le_userid` int(10) NOT NULL,
 `le_time` int(10) NOT NULL,
 `le_ip` varchar(50) NOT NULL,
 PRIMARY KEY  (`id`)
) ENGINE=MyISAM;

If that works, you are going to have to do that for all tables created in the modification where the engine type is specified.
