Were you ever able to solve this issue? I am experiencing the same.
Why am I not able to order my book after preflight?
After my indesign file goes through the preflight stage nothing happens and I'm not able to order my approved book or view it on my blurb detailed books page.

I've tried to do everything outlined to order my book - downloaded new programming, firewall off, & security closed.
