Can't open the app

Hi forum readers,
I have a problem with the WaveLab 8 LE, wich I got with my hand recorder (Zoom H1)
The problem is, that I can’t open the app. After I click the shortcut on desktop, the prompt window pops-up and requires a registration. So I click that registration button, it takes me to the steinberg web, here I fill everything needed to continue, and then, after I enter the eLicense key, it looks like OK, but when I click again the shortcut and then it all repeats.
