Internal FM error 7104, 7256027,4752735-Any fixes?

[archana sathiyamurthy]

Greetings Framers:
 
We are working on a FM book file with eight chapter files in it.We have to update a few of those chapters with new contents.
 
After we made changes to the respective chapters and tried to update the book, we encountered the following errors:
 
Internal FM  error 7104, 7256027,4752735
 
FM automatically closes after we click OK for the above error dialog.
 
Also,the error log report showed some fonts as unavailable.We unchecked the check box "Do not remember missing fonts" under File>Preferences>General, assuming this would solve it.But no luck there!
 
We even tried copying all the contents and generated the book file from scratch, but it did not work too.
 
I can't think of anything else to fix this.
 
Please let us know if there is any solution or workaround for this.
 
Thanks in advance,
Archana
