After all my work creating in LR book module, I cannot send the created book to Blurb using the button in lower right corner. Halfway through the process, I get this error message: "An error occurred while creating the book". I have retried many times. For info, I can export the book as a jpeg to my hard drive. I thought I may be able to save the book in pdf and then upload to Blurb on their website. However, I cannot even export the book as a pdf to the hard drive. I have save other pdf files so I really don't know what is the problem. I saw that some were reporting this problem a few years ago. Any advice would be appreciated. Thanks.
Thank you for your prompt response. I spent all day going through the solutions in both threads you attached. A lot of good info though, but nothing worked for me. I am a long time LR user and have made a number of books using other vendors. But this is the first effort at using the LR Book module and Blurb. I think I have spent too much time and effort trying to send this book to Blurb and exporting as a pdf from the book module. Will go back to my other book printers.
