Hi Markus, can you please download this file: http://moi3d.com/temp/ForPaul5.zip and copy those new versions over to your MoI install directory and see if it fixes the problem?

Another user reported the same problem as you, and it turned out that he had a quirk in his registry that broke MoI. The updated above fixes MoI to not rely on this particular Windows registry entry.

Please let me know if that fixes the problem for you or not.

Thank,

- Michael
