I originally installed Logos 4 on a Windows XP virtual machine (VMware Fusion 3) that also has my Logos 3 installation. My Logos 4 resource count (on XP) is 4377. This past weekend, I "upgraded" Win XP to Win 7 (basically a clean install of Win 7) and eventually installed Logos 4. Now my book count is 4308, 69 less than my Windows XP installed.
I now know that 59 of the missing resources are of the old Logos 2-LIX/LSF format. I'm not sure of the remaining 10 missing resources; I'm guessing that they are also from that same era of Logos Library System books. Apparently when I installed Logos 4 on XP, it download 4308 books that I own of the Logos3/Logos4 format and imported 69 books of the ancient format from my Logos 3 installed. And since there was no Logos 3 on my Windows 7, Logos 4 just installed the books I have from the server. Then I WRONGLY assumed that just copying and pasting the missing books into my Windows 7 Logos 4 install would trigger an indexing of the LIX/LSF resources and add them to my library!!!
So my question is, "How do I get my Logos 4 on Windows 7 to recognize my old LIX/LSF resources? I hoping for something well short of starting all over by installing Logos 3 first in Windows 7 followed by installing Logos 4 again!!! 
(by the way I'm still running my XP virtual machine, just in case there is a file or folder I could copy from Logos 4 there to Logos 4 on Win 7...)
