Disk images failed to mount
 

Hi, I am a new iMac user and have burned only 2 CD's so far. I am using Mac OSX Panther 10.3. I downloaded ILLEGAL ACTIVITY

for my friend, but when we tried to open each, whether from the desktop, the shared file, or the burned CD, we got a "Waraning - Disk Images Failed To Mount" "no mountable file systems." Can anyone help? Thanks
