I've added a new PBB book and it is in my Library now. However, I have made several changes to the .docx file and now it won't rebuild. I get the error message that the "Build failed. Could not remove existing resource. Please close all other open panels and try again."
I have closed every open window and I still get this error message. I have deleted the link and re-add the file and it still does not re-build.
What can I do to re-build this PBB book?
