[SOLVED] Page links not work..

[eluser]predat0r[/eluser]
I just put online a site, but when i click on the menu links, the url changes to the appropriate link, but the page always remains at the first starting page.
I use the following .htaccess file that works for other site

Options +FollowSymLinks
RewriteEngine On
RewriteBase /subcart/

RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index.php?/$1 [L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

the temporary demo site: .deleted.

thanks

EDIT: putting manually index.php in the URI links work. So something has changed in CI 2.0 , trying find out what happened.. i dont want to use "index.php"

EDIT 2:
solution is modded .htaccess:
