SEO URLS not working?

I have just installed 1.29, but am having troubles getting the SEO URLS to work. I have enabled, and have changed htaccess.txt to .htaccess, and my htaccess says

----------------------------
Options +FollowSymlinks

RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)\?*$ index.php?_route_=$1 [L,QSA]

php_flag magic_quotes_gpc off
php_value memory_limit "128M"
----------------------------

Still not working though, any help
