Solution I was given for the same problem: BW spring cleaning
I had the exact same problem awhile ago. Jim Wert showed me that what was needed was to get BW to do a self-cleanup. Close down BibleWorks, and then (quoted from Jim):
- Hold down shift key, click on BW9 icon, holding shift until the "BibleWorks Trouple-Shooting Options" window shows up.
- Under "Option 1" select "Rebuild Version Data" (This is to get BW to reinitialize stuff without messing up any settings I don't want clobbered. It is the least invasive of the available options.)
- Click on "Perform the selected options and run BibleWorks".
This did the trick for me, and it was quite simple to do.
The entire discussion (with a couple of false side-trails) is here; Jim's answer is in post #8.
