If you get a "Return Code 266" when you try to use the TBCD player or Sierra,
follow the steps below to correct it. 

    1) Make sure that you have an Audio CD in the CD-ROM drive, not a 
       data CD-ROM.  
    2) Open Main -> Control Panel.
    3) Select "Drivers" and click on "Add."  
    4) Choose "[MCI] CD Audio" from the list and click [OK].
    5) You will be prompted to insert one of your original Windows disks in 
       the drive.  Insert the disk and click [OK].  
    6) The driver will be copied to your hard drive and you will be 
       prompted with a "One CD-ROM detected," message.  
    7) Close the Control Panel and try the TBCD player or Sierra again.
