Error message - Bibliothek nicht registriert/ Library not found
February 3, 2015 12:00 AM
Hello there,
my confusion level is at its maximum. So out of nothing I get, upon opening one of my lectora courses, the error message "library not found" (see image 1). Suddenly I couldn´t open several of my courses, although everything was working fine a month ago when I opened them the last time. Strangely there are courses which work just fine. And my colleague can open all the course files, which give me the error message, on his PC without a problem, although he uses the same exact files (our company uses a central project archive supported by a revision control software, so the shared files are identical) and the same version of Lectora (11.3).
There are also Lectora courses which work partially. Which means I can open the file without a problem but the error message appears as soon as I click on a page (see image nr. 2). When I unfold the page I can see the content of it, like images or soundfiles. But as you can see the page itself is actually blank (image 3). Inherited objects like the pagetitle, the logo are still there and I can edit them. But they are positioned outside the structure of chapters and pages anyway. To add to the confusion there are pages in that broken course which work fine (see image 4).
So somehow the connection between page and content is broken but I really have no idea what the source of this problem could be. Strangely all the assets are still listed in the resource manager (image 5).
Do you have a solution for this problem?
FIXED: The Flashplayer was the source of the problem. I installed the flash player on my internet explorer (although I had one for firefox, but somehow that didn´t count I guess) and now I can open the courses again without getting a error message.

Guten Abend :)
If your colleague can open the file without problem, this means the files are ok (make a backup! now!) - and there is a problem with your Lectora install. I would start with just re-installing Lectora and seeing if it helps.
Also, I think sometimes special characters (such as umlauts in German) in file names can cause similar behaviour.
So I think I got closer to the issue. I found out that the problem arises in all courses with media-content, which can be audio and video files.
What does Lectora internally use for playing those files and how can I fix it? I already reinstalled quicktime but that didn´t fix the problem so far.
Hi Sergey,
thank you for your answer. Should´ve mentioned it but I already reinstalled Lectora several times. Even deleted every remnant file I could find, but unfortunately it didn´t solve the problem.
We use Umlaute in our Lectora files only on page titles or in the text itself, not in the added object, e.g. images and audios. The only Umlaut-related problems we had so far, were that our server can´t recognize them. Because of that we are mindful to name them only with small case letters and without special characters.
One of the courses I can open without a problem does even have Umlauts in the title. So I don´t think that its causing the issue.
