Domain Problem

My forum is www.chiefs.omgforum.net and its called Arrowhead Drive.

I purchased the domain www.arrowheaddrive.com from 1and1

I changed the CNAME on 1and1 to chiefs.omgforum.net and I also changed the Personal Domain Name on my forum to arrowheaddrive.com

It is not working though, what is the problem?

Now its getting even more crazy. I put the URL in both firefox and IE and it goes to the screen saying this domain has recently been purchased or what not. I told my friend I'm having problems getting it to work and he puts in the URL on his computer and it works for him.. so I asked him to copy and paste it to me and this is what I got - http://www.arrowheaddrive.com/index.htm

and it worked for me when I clicked that. ???
