Since a PDF should be fully compatible from on eto the other, we're going to need a lot more info.
How is the file being created? What version of Reader are you using? If on a Mac, are you actually trying to open the PDF using Reader or are you using Mac Preview? How are you trying to open it (downloading and double clicking, double clicking from within an email, downloading and using File>Open...etc)? What exactly happens when you try and open it?
The more info you can add to the above questions (and please, answer all of them not just one or two), the bette the chances to figure this out.
The PDF was mailed to mail in mac using outlook in windows.
It doesent show anything when trying to open it.
I have tried both preview and latest verson of adobe reader.
Its the latest verson of everything, macos and windows XP.
PDFs don't like very much tra
velling through the internet. Ask for the file to be zipped before reposting.
