Unable to Extract from Chinese PowerPoint

["Ahmed, Sana R (IS)" <Sa...@ngc.com>]

Hi.
 
I am trying to use the PowerPointExtractor class to extract text from a Chinese powerpoint document.  I have been able to successfully extract text from other Chinese powerpoint documents, but with this particular document I am getting the following exception.
 
The Current User stream must be at least 28 bytes long, but was only 7
not continuing anyways
org.apache.poi.hslf.exceptions.CorruptPowerPointFileException: The Current User stream must be at least 28 bytes long, but was only 7

I know that this is a valid PowerPoint since I am able to open it up and view it using Microsoft PowerPoint.  This issue is happening with a handful of files  What could be causing this problem, and how can I overcome it?
 
Please let me know.
 
Thanks!
 
Sana

Is it really a powerpoint 97 or newer file? You most commonly get this 
error when trying with really old powerpoint files (pre office 97). Try 
re-saving it as powerpoint 97 and try again
