Cache Router doesn't work - trying Xcache and APC

My settings:

$conf['cache_inc'] = './sites/all/modules/cacherouter/cacherouter.inc';
$conf['cacherouter'] = array(
'default' => array(
'engine' => 'xcache',
'server' => array(),
'shared' => TRUE,
'prefix' => '',
'path' => '',
'static' => FALSE,
'fast_cache' => TRUE,
),
);

(just waiting for some replies to my posts on Cache Router

I really can't get Cache router working.

1) I get the following error, depending on the configuration 9x
warning: Invalid argument supplied for foreach() in /home/controlc/www/sites/all/modules/cacherouter/engines/xcache.php on line 122
warning: Invalid argument supplied for foreach() in /home/controlc/www/sites/all/modules/cacherouter/engines/apc.php on line 121

2) I cant find any menu entry for configuring Cache router as it is shown on the module page

$conf['cache_inc'] = './sites/all/modules/cacherouter/cacherouter.inc';
$conf['cacherouter'] = array(
'default' => array(
'engine' => 'xcache', (or 'apc')
'server' => array(),
'shared' => TRUE,
'prefix' => 'ccg',
'path' => '',
'static' => FALSE,
'fast_cache' => FALSE,
),
);

Please, Help!

Thank you
