This message occurs if you try to use, as part of a Quark Pages script line, a QuarkXPress file that was last saved using the short-lived Middle-East version of QuarkXPress 6.
Solution
To our knowledge, there is no solution to this problem as files that were created with that version of QuarkXPress can not be opened with any other version of QuarkXPress.
