I just paid for a minimal crossgrade to Logos 4 a few weeks ago. Before I even get it to work now I find out it is obsolete. I wish I could go back in time 20+ years ago when I bought my first Logos 2.0 software. Back then they promised the library software would always be free. I would definitely tell myself not to do it. Over the years I purchased many titles which are now included "free" in various packaged libraries. And they want to force me to repay for them again in order to upgrade my library. I refuse to do it and go with the "minimal" charge ... and find I have been ripped off on that too. I have been fooled too many times by this money sucking scam.
I just bought a new computer and I am having serious thoughts of not even installing this buggy mess of overpriced half-completed vaporware.
