One of the problems with using PDF may be that you're not making it compatible enough. I have the full version of 4.0, but am not permitted to view the document.

PS; after spending 6 years as a prepress professional, I can probably make most of these templates as fast as you can find them. However, most of the jobs I've seen that the outsider folks (graphic artists) either cannot, or will not take the time to figure out how to put something multiple up on a page, or fold properly. PLEASE use these templates, they're going to be much better than a graphic artist who "eyeballs" it.
