Unable to download the whole book PDF

[epeltz33]

Hey I first want to say this book you put together looks like its going to be super useful and helpful and I want to thank you for your hard work creating it. When I click on the link to download the whole book as a pdf I am getting an error saying "unable to render rich display Invalid PDF". I am not sure why this error is occurring but I thought I would let you know. Here is a screenshot of the error.
thanks again

Hi, thanks for reporting. Did you click Download button? It works for me. Maybe try a different browser?
