Snapshot plugin giving Error 500

I just installed Snapshot Pro for on WPMU. I've tried running it twice and both times I'm getting an error
Error 500 - Internal Server Error
An error was encountered while processing your request. Typically this is a temporary condition. Please contact the web site owner for further assistance.

It progresses almost to the bottom, but it kills over at 60% on "Files: plugins".
My MU site is really, really small as I've only been tinkering and haven't really made anything public yet.

    Hi there,

    Hope you are doing well today and thanks for asking! No worries, it's a common issue due to insufficient memory and should be fixed if you increase your memory limit. But first let's identify the issue. For this I need you to enable WP_DEBUG in your wp-config.php which is in the root of your WordPress install. http://codex.wordpress.org/Editing_wp-config.php#Debug

    1. Enable debug logging. You can do this by adding the following lines to your 'wp-config.php' file:

    define('WP_DEBUG', true);
    define( 'WP_DEBUG_LOG', true );
    define( 'WP_DEBUG_DISPLAY', false );

    2. Increase WordPress memory limit:

    define( 'WP_MEMORY_LIMIT', '256M' );

    3. Add the following lines which are specific to Snapshot settings:

    define('SNAPSHOT_FILESET_CHUNK_SIZE', 10);
    define('SNAPSHOT_TABLESET_CHUNK_SIZE', 100);
    define('SNAPSHOT_FILESET_LARGE_FILE_SIZE', 104857600);

    4. Increase max execution time to 300 or more by trying the following methods.
    a. Create or edit php.ini in your website's root and add the following line:
    max_execution_time 300

    b. In .htaccess add the following line:
    php_value max_execution_time 300

    c. in cPanel you can go to "Software > MultiPHP INI Editor", choose your domain and PHP version and change the value for max_execution_time to 300 or more

    After that you can try Snapshot again. Hopefully everything should be fine. Let us know if you still face any issue.

    Have a nice day. Cheers!
