I've posted a similar question in the General Forum, but perhaps this is a more appropriate place for the question.I have just successfully upgraded from Logos 3 to 4 on my PC earlier today. It runs fine, and it also works fine on my iPhone.
However, I am having problems with my Mac (Macbook Pro with Lion). I've installed the Mac version of the software and it runs identical to the PC, but it is empty of books.
When I click on my user name it takes me to the Logos online store and confirms my account details and the books I've ordered. But it does not populate the Mac Logos engine.
