It's protected with one of the more recent releases of securom and both clonecd's virtual drive and hide cdr media are blacklisted.
The blacklist against the ccd virtual drive is effective if it is installed on the system even if not active. However, the blacklist against hide cdr media is only effective if hide cdr media is running.
If you want to run the game with ccd on your system, you need to unistall ccd and then do a custom re-install omitting the virtual drive component.
Once you've done that, you need to disable hide cdr media [note that this must be done from the tray icon and it isn't sufficient to just close the tray icon; if you just close the tray icon without first disabling hide cdr media it will still be running].
