Wiki plugin file not found

Hi WPMU,

I just installed the wiki plugin, however when I go view the test wiki page. It came back with "File not found".
I have a few other WPMU plugins installed and running buddypress. Could someone please help me to have a look on the issue. If needed I can email or message the login details.

Thanks and Regards,
David
