Drastic changes happened
I changed Permissions for the whole Mac HD and the problem was fixed, and iTunes imported the CD. After that, I connected my iPod Touch to synchronize it, and I receive an unexpected box saying "Can not connect to iPhone --- error ----"
So I decided to reboot and once I did, the login screen never showed up, and it was only the welcome screen with the apple in the middle, every 2 minutes, it automatically reboots, as if it was a loop or something.
I read the Everything Mac booklet, I tried rebooting while pressing the Option key, did not work!
So I reinstalled the system, using the disks that came with the laptop (disc 1 and disc 2)
Currently, I am updating the software... and did not try to import a CD yet... fingers crossed
