Hi, I am having difficulty in adding a docx file to one of my already built personal books. I previously built the book and afterwards try to add an additional docx file using the add file button and then get an error when I click on build book: [Info] Starting build for PBB:32deb19179f84b48b423840b438c3e5c [Error] Error while building book: Could not remove existing book. Please close all other open panels and try again. [Error] Exception: LDLS4.Panels.PersonalBookBuilderPanel.PersonalBookBuilderException: Could not remove existing book. Please close all other open panels and try again. at LDLS4.Panels.PersonalBookBuilderPanel.PersonalBookConverter.CreatePersonalBookWork(PersonalBook book, PersonalBookBuilderViewModel model, PersonalBookViewModel bookViewModel, IPersonalBookBuildLog buildLog)+MoveNext() at Libronix.Utility.Threading.AsyncWorkerTask`1.EnumMoveNext() at Libronix.Utility.Threading.AsyncWorkerTask`1.EnumMoveNextWithCatch() --- End of stack trace from previous location --- at Libronix.Utility.Threading.AsyncWorkItem.Verify() at LDLS4.Panels.PersonalBookBuilderPanel.PersonalBookViewModel.CreatePersonalBookWork(PersonalBook book, PersonalBookBuilderViewModel bookBuilderViewModel, PersonalBookViewModel bookViewModel)+MoveNext() == I dont have any other instances of logos running and all open tabs are closed except for personal books tab I am trying to edit. What am I doing wrong?

  1. Nothing. This is happening when building PBs. You simply need to restart Logos, then it's good again.
