Admin page inaccessible after plugin update

Hello guys, I just updated the plugin a while ago and it crashed my admin page.

I am a complete newbie in anything technical related so I need assistance on this one. Deleted the update and reuploaded an older version but to no avail. I am currently getting an error like –

[15-May-2013 13:39:42] PHP Warning: require_once(/home4/thesolit/public_html/wp-content/plugins/w3-total-cache/lib/W3/Config.php) [function.require-once]: failed to open stream: No such file or directory in /home4/thesolit/public_html/wp-content/plugins/w3-total-cache/inc/define.php on line 1426
[15-May-2013 13:39:42] PHP Fatal error: require_once() [function.require]: Failed opening required ‘/home4/thesolit/public_html/wp-content/plugins/w3-total-cache/lib/W3/Config.php’ (include_path=’.:/usr/lib64/php:/usr/lib/php:/usr/share/pear’) in /home4/thesolit/public_html/wp-content/plugins/w3-total-cache/inc/define.php on line 1426

I would really appreciate help on this one guys.
