Renewing Subscription for NAV 2006

One of my computers is an older one running NAV 2006 and XP SP1.  I have about 6 months to go on the curernt subscription but I was wondering if I could simply renew it again when the time comes or would I have to get a later version?

 

I've had to keep SP1 on this one machine for other reasons and the NAV 2006 works just fine on it so I'd like to keep it going, if possible. 

 

 Will I be able to just renew it and continue to get definition updates? 

 

Thank you-
