Nothing dissapears by it self. Somebody did do something to your site or server. Don't blame the extension.
By the symptoms you describe the most probable cause is a Joomla upgrade not following the manual or a PHP5.3.x upgrade.
The first is described in the manual - in short: uninstall M17n, upgrade joomla, reinstall M17n. All with the FTP layer enabled.
The second can probably be solved by using the betapatch on the site. But hey... that's Beta.
Anyway... always read the manual first... and if you have any questions, please ask these questions first... then shoot.
