Hi
Actually I emailed our dev team when this case was created. Unfortunately, we have had a full plate for the last week and a half so it might have been missed in the deluge of emails I had to send in.
I realize you are having troubles and hope we can help solve them but it seems unfair to flag a plugin as broken when since I started here I have only seen three cases about the wf_hoover file, and the other two don't seem to be what you are experiencing.
Let's see if we can sort out whats going on. What version of the plugin are you running? What version of Wordpress? Was the plugin working vbefore and stopped working? Was there any changes before it stopped? I see you are using InnoDB instead of myisam. Is this correct?
Thanks!
