PDF Generation

Hi,
I'm trying to generate a PDF using fpdf but I get an error saying: the file is damaged and cannot be repaired. And thats just by using the demo file.

Is there anyway I can get a pdf file created once I click on my page. I'm trying to create a business card designer, I have created it. but next step is create pdf

Also I'm using a javascript that allows me to move the content in the iframe/layer how do I add the position of the text to the pdf file?
fpdf seem very complicated :'(
Help!!
