Answer 1

Maybe the .htaccess is not in the correct directory.. you may want to check it, should be inside your project directory. if so,
put this in your .htaccess file
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]

Answer 2

You might want to also check your httpd.conf file and see if apache is allowed to "honor" your .htaccess file. Search for the AllowOverride command and change it from AllowOverride None (the default) to AllowOverride All.
ALSO: Do not forget to restart the httpd server afterwards.
