Visualization never stops initializing

[jm-fh-402]

I have a question about getting Windows 7 to show me the visualized data set. It was no problem installing it and despite the fact that I cannot see anything in "Overview", there seems to be no further problem. I tried to open some example data and there was no problem at all and I can also see all the data in the "Data Laboratory". But the window in "Overview" alsways keeps initializing and it doesn´t stop.
Does anyone have a answer why it is that way and how to fix it?
Of course I did all the updates and my Hardware is good enough to run it.
Thanks.

Looks like a graphics card problem, please try to update your drivers.
