What worked for me:
[sql]INSERT INTO `usergroup` ( `usergroupid` , `title` , `description` , `usertitle` , `passwordexpires` , `passwordhistory` , `pmquota` , `pmsendmax` , `pmforwardmax` , `opentag` , `closetag` , `canoverride` , `ispublicgroup` , `forumpermissions` , `pmpermissions` , `calendarpermissions` , `wolpermissions` , `adminpermissions` , `genericpermissions` , `genericoptions` , `attachlimit` , `avatarmaxwidth` , `avatarmaxheight` , `avatarmaxsize` , `profilepicmaxwidth` , `profilepicmaxheight` , `profilepicmaxsize` )VALUES
('404', '404''d Users', 'Users who see 404 errors whenever they try to access the board.', '', '0', '0', '50', '5', '5', '', '', '0', '0', '127487', '3', '19', '1', '5319', '30', '7', '0', '80', '80', '20000', '100', '100', '65535');[/sql]

EDIT: Note: I modifed the discription of the usergroup, but it's not important.
