Re: MYSQL error (errno: 145) Hope you have buckup for every db file, you should delete mos_session from your mysql and upload the new one, if you dont have you can create one yourself in the notepad.
Here is how should looks, then drop the old one upload this one it will works. #
# Table structure for table `mos_session`
#
DROP table IF EXISTS mos_session;
CREATE TABLE `mos_session` (
`username` varchar(50) default '',
`time` varchar(14) default '',
`session_id` varchar(200) NOT NULL default '0',
`guest` tinyint(4) default '1',
`userid` int(11) default '0',
`usertype` varchar(50) default '',
`gid` tinyint(3) unsigned NOT NULL default '0',
PRIMARY KEY (`session_id`),
KEY `whosonline` (`guest`,`usertype`)
) TYPE=MyISAM;
