I purchased logos back in 2006 or 2007 I have always been updated. When you changed your software a few years later I want to say in 2009 or 2010 it crashed my computer. I tried again to download it to my apple thinking it's 2018 it has to have gotten better and continued to have problems. With not opening but constantly opening without anything else happening? Is this a known problem? I am online with the basics is this enough to access all of my books? I am on a MacBook Pro.
