I assume since you have an open case # that means you have already contacted Logos Tech Support. If so, I am not sure why you are posting this problem in the forums.
Also it is not clear what action you have taken i.e. did you try the command to rebuild the library index or did you delete the library index folder (the latter is indicated if not already attempted)?
What Fred and Dave are both saying is that whilst there are Logos staff on the forums from time to time, the majority of help given comes from volunteers who have no access to any information you've already given Logos' customer support.
So you could either follow up your query by email with them, or you could start again with us by explaining exactly what problem you're having. But without all the information, we won't be able to help you here, sorry.
Bryant has another thread for this issue...
In addition to what the others have suggested, you should continue to use that thread.
Bryant had several threads, further adding to the confusion over his intentions.
My sincere apologies to you all. Logos was dead in the water, I was in the midst of three crises, was working with support and could not get the logs directly to them, so posted here for their retrieval.
The 6.4 SR-3 (6.4.0.0065) update seems to have resolved the problem when even a wholesale removal and reinstall with their direction didn't.
Glad to hear it is up and running! [:)]
