ParagonPPT

I own two domains, bought here on squarespace: www.paragonppt.com and www.paragon-online.com My website was originally through a company called PatientSites, but their services were no longer needed, so I cancelled that subscription. It took a month for them to take down the site, and so in the meantime I was building my new site HERE, at paragon-online.com. This site has been up and running fine for the last few weeks. I just went in and changed the domain from paragon-online.com to paragonppt.com and now NEITHER links to my new squarespace site. Is this simply something that takes 24-48 hours to take effect, or did I break the sucker?
