Thread:Project:Support desk/Can't run Update

I've tried to install two extensions that require an update to the database tables (Liquid Thrheads & Advancedmeta) and the update fails with the following error messages for each. Warning: include_once(languages/SMW_LanguageEn.php) [function.include-once]: failed to open stream: No such file or directory in /home/content/65/6092565/html/scientolipedia/extensions/SemanticMediaWiki/includes/SMW_Setup.php on line 508

Warning: include_once [function.include]: Failed opening 'languages/SMW_LanguageEn.php' for inclusion (include_path='.:/usr/local/php5/lib/php') in /home/content/65/6092565/html/scientolipedia/extensions/SemanticMediaWiki/includes/SMW_Setup.php on line 508

Fatal error: Class 'SMWLanguageEn' not found in /home/content/65/6092565/html/scientolipedia/extensions/SemanticMediaWiki/includes/SMW_Setup.php on line 512

I posted this on the Semantic Bundle page and Yaron Koren said he didn't know what was causing it but suggested I install the newest version of Semantic Bundle, which I did, but still get the above. Any help is appreciated.

MediaWiki 1.18.0,PHP 5.2.17 (cgi-fcgi),MySQL 5.0.92-log, Semantic Bundle (Version 20120308)
