I am having trouble getting the Centova module to work with the new Customer and Business feature of Plesk 10, which appears to have taken the place of the old Plesk Billing system.  When I copy the centovacast.php file to the Plesk modules directory, the panels page won't load.  I suspect that perhaps in my efforts to follow directions, I might have overwritten a Centova file that was already in the folder, and the one designed for Plesk Billing 5 won't work with the new Plesk system.  If that is the case, is it possible to download the newest centovacast.php file for Plesk anywhere?
