This issue may occur if one of the following conditions is true: You are not

• using the game disc to start the program.
• The CD drive is incompatible with the program.
• You are using a copy of the program CD.
• You are not logged on to the computer as an Administrator.
• The program or programs are interfering with the game startup that is running but is invisible to you.
• You are running a Microsoft Windows XP Home account that uses "fast user switching."
• The CD drive is using outdated drivers.
