Why do you even have that on your system? Get rid of it and see if that fixes it.
You didn't use Acrobat to create that file. It was created by exporting to PDF from InDesign which causes all of the fonts to be converted to CID format. Try printing to a PostScript file from InDesign, then use Acrobat Distiller to convert to PDF. Do you still get errors from that?
BTW I had no problem opening the file in Win2K using either Acrobat 4.05 or 5.05.
It now appears that the problem is related to Adobe Acrobat 3.0 which I use to create PDF files. The reader works if I uninstall Acrobat and visa versa. I would like to fix this problem without having to upgrade Acrobat since it otherwise works, and I don't like the idea of companies forcing upgrades in situations like this.
Any suggestions?
