Hi . . . anyone know how to view PDFs from e-mail. I need a good App, does the app need to sync or be setup with e-mail to open, is there a size limitation?

I've installed Beamreader (just did a standard install, nothing about my e-mail app weas asked), I have a PDF attached to my e-mail, at the bottom is a button to view. When I press it I get a loading screen which stays on for about a min or so and then disappears and returns to the e-mail . . . no PDF view.

Any ideas or suggestions? How long should is take to load for viewing? thx
