Title of this post pretty much says it all.
The zipped files provided for download would unzip to folders "LibSpellName2SID-1.1.04" and "LibSpellName2SID-1.1.04-Passives", whereas the .TOC files inside were named "LibSpellName2SID-1.1.toc" and "LibSpellName2SID-1.1-Passives.toc"...
1.1.05 has been uploaded and corrects the problem.

I apoologize for the inconvenience.

As a bonus, the databases now include some (not yet all) of the Azerite Essences introduced in WoW 8.2.0.
