What does this error message mean?

I'm trying to edit an old X5 file. X6 crashes near the end of trying to open the file. X5 gives this message:

---------------------------
CorelDRAW X5  Condition #1002-D:/WALDO/V1500/ENGINES/CRLUTL/LISTMAN-0760
---------------------------
Unexpected condition encountered.  Please refer to the Technical Support Help.
---------------------------
OK  
---------------------------

Is the file corrupt/gone? Thanks.
