NASB, which I purchased and NIV were gone from the tabs but the files are present.
I updated NASB with my old key info. Which works.
As for NIV, it was an old conversion I obtained from the web. So, it took me a while to hack it. The solution lies in the software SQLitebrowser. Thanks to this link, I was able to solve it. All I have to do is to change the abbreviation of the module under Browsedata (from niv to something else). I do not know the need to do this since there is no conflicting abbreviation in my collection with "niv". So, I could only guess that it is a copyright measure? or perhaps conflicting with the real version in the download listing.
Much time has been spent solving this, now I have to rush my other errands.
