A support thread for this would have been nice instead of a one star review, particularly when there are so many other four and five star reviews (so the plugin obviously works for a good number of people).
Generally, a blank PDF implies that another plugin is interfering with us getting the content. Thus, we generate what we see, which is a blank page. I’m happy to work with other plugin developers to fix these situations, and have done so in the past.
If you are still willing to give this a try, please install the latest version (I just pushed 1.1.0 today), and open a support thread if necessary, or contact me through my blog, as the documentation directs for official support. I’m happy to help.
Cheers
Lewis
