I am running Logos 5.1b on OS X 10.8.5. There is a Logos icon at the top right of the screen with the option to install an update. When I select to install the update, a pop up window appears and it says version 4 updates being installed. After I use this update tool, Logos will not run again until i reboot the mac book. The update popup hangs until reboot too. Please advise?
