Some PDF files will not open in LO Draw

I cannot open about 10-15% of PDF files with LO Draw and I cannot figure out why or when it will happen. I could attached samples to illustrate the problem. These files can be opened in every other application, including browsers, but LO Draw will only show an “input/output error” when trying to open them. Can anyone figure out why?

If you have already fulfilled some of these requirements, so much the better. Thanks.

Thank you very much for your assistance.

At moment only the person(s) with access to your 10%-files… So upload some (start with a smaller file) or buy some books on postscript or pdf-internals.
