Can I trash expired NIS?

I installed NSBU last December on top of my then active NIS, in order to keep all the NIS settings including my local vault. (And how is it doing, by the way?... wink  )

Now, when I visit my Norton Account, the NSBU correctly shows as the active protection but NIS remains there, showing as "Expired" and asking for a renewal. I can easily take it out by clicking on the trash bin at the side, but will this action affect in any way my NSBU settings? I believe it will not, but thinking of all the trouble I had in the not so long past to "recover" my "lost" local vault, I want to be sure I won't get into it once again...

Please help.
