I have created a email and sent it to them and now it says the following error message.
Adobe Reader could not open 'Josh.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).
How do I re-send it? This solution - http://helpx.adobe.com/indesign/kb/cannot-open-pdf-file-acrobat.html doesn't make sense because I've already saved it that way. Is there anything I've missed?
