I installed Marble on my home PC, Windows 8.1 Pro and my Office Windows 10 Pro.

Both do not function in any reasonable measure. Pick any map and you get the World View. NOTHING loads for ANY zoom into anything. Pathetic NON-Function.

Of course I suspect I will get some dressing down about some "obvious" Marble requirement. But it is most disturbing that you install and get essentially NOTHING. But well, I did not pay for anything... so I guess that is to be expected... yet I would PAY something to get away from GOOGLE!!
