do you mean if I try to access the script from the browser? If so, it doesn't do anything - its like the script isn't there. Very weird.
Likewise, if i 'run now' from admincp/scheduled tasks, nothing happens - the window doesn't say anything at all, just sits there on the scheduled tasks page with the eggtimer flipping itself over and over. However if I change settings inside vbox.php it throws an error when I go to run the task manually, so it is there...
