Windows registration problem...

[alavahalf]

Having had a problem after deleting a drive partition ... I decided to re-install windows xp.
The recovery disk has been inserted and I have got to the point where you have to register.
The problem is I am at the point where you have the choice of registering now or later, But I cant make this choice as the ..NEXT.. button is not visible on the screen, its as though all of the screen is not visible, and the bottom of the screen is hidden..?.
Now I cant restart or progress to the next stage.
