This sounds like the version of the DWF file or one of the markup items got
corrupted. Autodesk DWF Composer is finding content it does not recognize.

On trying to open a DWF file worked on yesterday, the following message
appears:- 'This sheet contains markups created by a newer version of DWF
composer. You will not be able to edit the markups or add new markups to
this sheet'.
Can anyone explain why this has happened?
