Query re registered URL of premium edition

I've just paid for the Premium edition of the Webwiz forum software and was in the process of activating it, but had a quick question first:

My web designers have downloaded the free version to test it's suitability, and as we haven't finished the site design yet, all URL references are to a temporary address. If I register the software to the URL that it will be used on when the website is complete and ready to launch, will I still be able to use it on the test website URL?

Cheers.
