Can't activate Cubase LE 5

I am having trouble activating the Cubase LE 5 software. Every time I try, I am unable to go to the page to do so. I keep getting an “error on page” message when I do. How can I go about finishing this?

Have you created a MySteinberg account?
If you have not, do so and then go to the "activation section of the MySteinberg page

I have a same problem with Cubase AI 6 for a Yamaha THR10, please help us.
