Book upload won't start

Question

When I click on "send book to blurb" button, the task appear on the left upper corner of Lightroom but the progress bar don't move even if I wait hours.
Previously, when I made a book, I had to give credential and book description in a new window when I used this functionality. Now, this window won't appear when I click on the button. No authentification, no transfer. Seem logical...
Anybody know how to fix that?
Using version 5.2. Updated to 5.3 and the problem is still there

Answer 1

guys i had this problem also, when it came to upload the book i got the error message but had been billed for the book. the money does eventually come back into your account after about a week.
however, i did find a workaround for the upload error and was eventually able to make my order, i am now just waiting for my book delivering.
boot your mac into safe mode by holding down the shift key. once you are on the mac desktop, open your iphoto as normal and do a test run of your book to create it as a pdf to make sure it works.
then click on buy book, enter all your details and the book should upload without any problems and your order should go through. then just reboot your mac like normal to get back out of safe mode.
i found this out from talking to a guy who works at apple and he says it's a known bug but that they haven't found out why it happens to some people and not others. he said once you've made your first purchase on the store from using safe mode you shouldn't ever have to boot into safe mode again for any further orders that you wish to make.
i don't know if that part is true though since i've only made the one order but i think i would be tempted to boot into safe mode for any orders i make from iphoto in the future.
hope it works for you guys, it worked for me.
