Great golly....
I unlock the license and download the resources for Logos 3. Sync licenses and back them up.
Then I run Logos 4 on that computer (Laptop), and my desktop. Both download and update fine.
BUT!
My laptop has all .lbxlls versions of the Calvin 500, and the desktop has logos4 versions!
Good grief....what to do?
edit: I just deleted the lbxlls's, and scanned the logos4 and let it reindex.
