I had recently updated some newly downloaded resources and updated to Beta 5. Indexing was completed.
I tried to reproduce this bug http://community.logos.com/forums/t/47231.aspx to see if it had been fixed in Beta 5.
Oddly, the search described in that bug report (chart WITHIN 2 words sacrifices) did not find any hits in the NLT Study Bible, the subject of my earlier crash report.
So I tried a search for just israel in that resource and it found nothing.
Figured it must be a bad index problem, so I entered the command rebuild index and hit Enter.
Got a crash in the Indexer right away. See screenshot and logs. There was no new Logos4IndexerCrash.txt from today. I'm attaching all the logs that had dates of today.
