    Can't open files created in CS3 with CS4


      When I try to open a file that was created in CS3 I get this message:


      Cannot open the file "OpenEnrollSample.indd". Adobe InDesign may not suport the file format, a plug-in that supports the file format may be issing, or the file may be open in another application.


      This goes for both the InDesign files and the PDF files created with them. Does anyone have any idea why this is happening? Thanks for any help.
