Installation of plugin leads to warning error

[Title amended]

Hello Im desperately hoping somebody can help me?
I installed a plugin called neat-skype-status-pro and now nothing will display or work I keep getting the following message on every screen
“
Warning: require_once(widget/nssp-widget.php) [function.require-once]: failed to open stream: No such file or directory in /home/kjmathiesen/littleislandtasmania.com.au/wp-content/plugins/neat-skype-status-pro.php_/neat-skype-status-pro.php on line 83

Fatal error: require_once() [function.require]: Failed opening required ‘widget/nssp-widget.php’ (include_path=’.:/usr/local/lib/php:/usr/local/php5/lib/pear’) in /home/kjmathiesen/littleislandtasmania.com.au/wp-content/plugins/neat-skype-status-pro.php_/neat-skype-status-pro.php on line 83″

I can’t even uninstall the plugin because the page wont display.
