Admin Issue - NEED HELP!

I am not a web programmer and generally am not sure what I need to do to fix this isssue I am having when I go to my site admin. Can someone tell me what I need to fix?

This is the message that I am receiving. I have no idea where I need to start to fix this.

Warning: require_once(Spreadsheet/Writer.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/68/3335968/html/admin/index.php on line 6

Fatal error: require_once() [function.require]: Failed opening required 'Spreadsheet/Writer.php' (include_path='.:/usr/local/php5/lib/php') in /home/content/68/3335968/html/admin/index.php on line 6

We need more info.

Hi Rod,

What information do you need? This is the message that I received when I go to the link. I have no idea how to fix it.
