Moving From Ghost 15 to SSR 2013

On the verge of putting Ghost 15 to sleep ( has seved me well ) and moving over to SSR 2013.  One thing that worries me a bit is that once the year subscription is up, does RRS quit working.  I just don't see a need to pay a yearly subscription for software that really doesn't have to change much, unlike, say , Norton Anti-virus.

 

Thoughts please.  Need to get 8.1 backed up on Laptop.
