Anti-Splog Fatal Error

So I tried installing antisplog, and actually installed it roper but accidentally left the blog-suspended.php in the plugin folder/files which resulted main page with a blog spam notice. So I deleted the folder and tried again.

Now I reinstall and I get
Parse error: syntax error, unexpected T_CASE in /home/wp-content/mu-plugins/anti-splog.php on line 303

Any Ideas?
