Cadega ran a copy protection test and said it failed. i also got this message but havent figured it out yet.
A problem was detected with your CD/DVD-ROM devices. Some or all copy protected games
may not work correctly with your drives. Check the permissions on your CD/DVD-ROM device (in /dev). The device can be found in the /etc/fstab file.

In a terminal perform:

ls -la /dev/CDROM (where CDROM is the device for your system)

Make sure that all users have rx permissions. If users do not have rx permissions then add the permissions by running

The device may be a symbolic link to a second device, for example:

lrwxrwxrwx 1 root root 3 Mar 23 05:50 /dev/cdrom -> hdc

Here we can see that /dev/cdrom is a link to /dev/hdc. Be sure to check permissions on the symbolically linked devices as well

Well, you should read it and do what it says (always a good idea with error messages). Open a terminal and type 'ls -la /dev/cdrom' (/dev/cdrom is going to be a symlink to the actual device 99% of the time).

Well i'm posting here, because that command is not working in terminal. I was wondering if someone could tell me of another way to do this.

What do you mean by 'that command is not working in terminal'? What happens when you try it?
