This below files are stored in the compilation folder 

> includes\src\Mage_AdminNotification_Model_Feed.php,
> includes\src\Mage_AdminNotification_Model_Observer.php,
> includes\src\MSP_Common_Model_Feed.php

So first navigate to `<magento-root>\includes\config.php` and comment both below lines in this `config.php` file.

    #define('COMPILER_INCLUDE_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR.'src');
    #define('COMPILER_COLLECT_PATH', dirname(__FILE__).DIRECTORY_SEPARATOR.'stat');

Than after clear the cache and again do the compile form the admin.
