Apple Logic Pro /LogicExpress Discussion

I recently purchased Logic Studio 8 upgrade from Logic Pro 7. 
Everything seems to be going well except I cannot register the product. 
On the registration screen it is grayed out in the box to click on to 
register. I can only click on the register later box. I can click on 
the register later box then the program loads. I would like to register 
the program since after every five times I open the program I get this 
register now warning. Anyone knows how to correct this behavior?
