When I opened Logos 4 this afternoon, I was notified on a 200+mb download (update). Normal business, it has happened loads of times since I got the Logos 4 upgrade in November. The problem is that, this time for the first time, Logos keeps crashing while trying to start the indexing. That is, the download completed and Logos 4 restarted, per normal. Then it started indexing, but, within a few minutes, I got an error report saying that Logos had encountered an error and needed to close. I closed Logos, re-opened and it started trying to index the updated materials. Again the error message. I've tried it twice more, included re-booting windows. No joy, I just keep getting the error message and the indexing hasn't happened. What gives? Why the problem after so many successful updates?
