Whenever I save a Framemaker file, I see a dialog box that states: 

"The path/filename.fm.YYY that Framemaker wrote may be damaged." 

Where YYY is a seemingly random 3 character extension to the .fm file. Please see attached screen shot (.jpg file). 

Mysteriously, this file is not present on the hard drive. In short, I can't save any Framemaker files. 

What's wrong and how do I fix this? 
Internal Error 6004, 5340167, 5338343, 5358704. FrameMaker has detected a serious problem and must quit. 

A file named "d:\program files\framemaker 6\FrameLog_02.09.30_10.27.02.txt" has been generated which contains information that may help Frame development improve the product for future releases. 

I have tried reinstalling with no sucess 

tried saving to MIF and back to a binary again, no success 

FrameMaker has been installed and re-installed many times (on a newly formatted hard disk as well as on a different machine). The latest patches have been installed. The MIF import option has been tried. The "Remember Missing Font Names" option in Preferences has been unchecked. The results of all of this are still the same: FrameMaker continues to damage files on save or FrameMaker crashes on save. we have over 400 documents in FrameMaker format that are now essentially useless. Suggestions?
