I have a user named -anonymous- and when I go to delete it I get the message below, what do you recommend?

Warning: hcRequest::include(/home/c/a/catalyst/public_html/sld/packages/admin/users/delete/index.php) [function.include]: failed to open stream: No such file or directory in /home/c/a/catalyst/public_html/sld/hclib/mvc/hcRequestResponse.php on line 69

If I click on the name I get this:

<message>action/group/edit/description<param><name>name</name><value>Downloaders</value></param></message><message>action/group/list</message><message>action/group/create</message>
