Logos 5 was crashing on my MacBook Pro on every startup. Before it would load my startup page, the window would disappear and I'd get the not-so-friendly "not responding" notification in the Force Quit window. I decided to delete the application and do a fresh install, but when I open the newly installed software, it says I must upgrade to 5.2b SR-4 with a link to the Logos install page. Problem is...I can only install the version it gives me on there...which gives me the same notification. Any help available? Thanks!
