When is the deadline to register for NH primary?

Can someone confirm if it is 90 days prior to the election? And does this only mean democrats wanting to change to republicans, or does it inculde unaffiliated as well? The website is confunsing as hell. Here it is. http://www.sos.nh.gov/vote.htm#DEADLINES

I know the general election is same-day voter reg, not sure about the primary.

For some reason I can't access the website, but the best place to search for this answer would be www.sos.nh.gov... go there and look around for the elections division.
