If you STILL like Libronix and STILL like to buy from Logos, don't be fooled by the invoices they now seem (?) to give you.
The older invoices (weeks back?) had a section for Libronix (Old versions) that you could use to download your purchase to Libronix. This part worked fine; I usually had to re-download the license file to get the book actually validated in Libronix.
Today Unix mentioned a book that I thought would be good (Tov's articles on the LXX), but I couldn't remember if it was Libronix or Logos4/5 only. So I bought it (as I did the Anath volume earlier this week and then got a refund since not Libronix).
Since the invoice didn't have a Libronix section, I assumed 'no Libronix' and waited this AM to call and get it refunded. But then I checked the FTP site and there it was! I downloaded it, sync'd my licenses (which now work by the way), and that little puppy's now cuddled up in my Libronix library!
Cutting to the chase, I guess if you REALLY want the book, purchase it with the idea of a refund, then get the file name and see if it's on the ftp site.
I love Logos SOOOOO much, I just accept the masochistic (spelling?) procedures they come up with!!
