Reporting Service expiration

I have reporting services installed.
It is going to expire soon.
I need to have a non-eval version of Reporting service.
How can I get it?
Is there any other method so that the reporting service doesn't get expired?
Thanks in advancesee http://www.microsoft.com/sql/reporting/howtobuy/default.asp for details.
