Martin,
The CD may not have been closed properly. If that is the case, other computers may see the files on the CD, but may not read the correct data when pulling the files from the CD. Try burning another CD, and make sure the CD is closed at the end of the session. A friend of mine ran into this problem with his XP machine (although not specifically with FieldPoint IAK files).
Regards,
