Map a no show

[Jan Logan]

I have used carbonite for quite a long time, but now with Mists, my world map won't show. All I have is a black screen with the flight plan icons on it. I have reloaded, un-installed a couple of times and reinstalled to no avail. The mini map in corner is their but am unable to tell where I am going and of course have no "go-to"
Can you help me?
