Hi Susan and Mark,
I changed the GoDaddy nameservers to ns1.BlueHost.com, ns2.BlueHost.com this morning (Feb. 20), but I just went back to Godaddy and checked the nameservers, and it was back to the NS01 and NS02 DOMAINCONTROL.COM again. So I changed it back to ns1.BlueHost.com, ns2.BlueHost.com again and saved, and it seemed to work! Fingers crossed it stays that way!
Thanks so much Mark and Susan!
