Cant Load Cubase in my iMac

Hi guys this is really weird thing i have seen similar posts but nothing like I have. So I just installed Cubase Studio 4 plus dungle key for e’licenser all good but when i wanted to launch it really weird thing happened! At the beginning it looks like program is loading with all its features but at the end the program is missing. I can load Media Bay, Sound Browser, Loop Browser but actual program : tracks and all the rest is missing. Im attaching the picture for better understanding. Does anyone have idea whats going on?

Is it possible that Cubase 4 is incompatible with OS X 10.8.2 Mountain Lion?

What does it say on the box for system requirements…?
And what does the Steinberg knowledge base say…?

Oh bollocks,… IT IS INCOMPATIBLE!!!
