Sometimes paperwork issues can be the biggest obstacle...

I`m dealing with this one company that I have been trying to get to accept my paperwork for at least four months now. The problem is that I cannot figure out how to fill out the PDF they sent me still in 2012. At first I printed out the pages and faxed them to the company but they notified me that they needed it in the original PDF format emailed back to them. So I filled it out. For some reason it looks perfectly fine when I fill it out on Mac laptop - I can see every typed phrase but then when I save and send it to them - the project manager tells me that my answers are not visible. I tried on a PC computer but the same old story. I went to Kinkos hoping that their computers in some mysterious way would grant me the desired visible answers but nope. Still invisible. Well, I gave up and admitted to the company manager that I was unable to produce the required answers in the PDF file and the response I got - the encouraging: please try again... (: Should I try again? ):
