IWAR2 on Vista "Start whit Kelvins Head, no Menue"

Hi, i played IWAR a long time. No after years i reinstall it on my Vista whit Nvidia 9600GT.

I start it whit the IW2EoCGS.exe. That works, but after the trailer i only see Kelvins Head, the green backround whit lines. There is no Menu.

Pleas help no Nvidia or Vista update fix that.
