Hi (Using Joomla 1.6.1 installed fresh site today)

I install JoomSEF 4 Stable today and everything going fine.

After trying to update urls by pushing this button I got this error:

Fatal error: Call to undefined method JAdministrator::getLanguageFilter() in /home/site/public_html/includes/menu.php on line 113

I then tried to enable .htaccess file that was set unabled and then I got this error and site back end and front end crashed and got this errors:

Back end
Fatal error: Class 'JConfig' not found in /home/site/public_html/administrator/includes/framework.php on line 39

Front end error
Fatal error: Class 'JConfig' not found in /home/site/public_html/includes/framework.php on line 46

Any solution for this problems?
