Visualhub registration

hi all,
i legally just purchased a copy of visual hub, i got my email confirmation, however, the email instructions tell me to hit the "register" button on the welcome screen, BUT when i open the app it goes right to the application and there is no option to register and the app will not work till it do that...please help...how do i get that welcome screen to come up?

 

i tried that.....didnt work....when i use appdelete it deletes the.plist so i dont understand whats going on
