subdomain/hostname config problem

[pbw]

About 8 hours ago I created the subdomain account http://chandan.massinfluence.net and it works fine. But now everytime I attempt to create a new subdomain I instantly get a page cannot be displayed error http://wubby.massinfluence.net for example. The account is viewable by http://massinfluence.net/~wubby/ however.
Any advice or tips you guys could lend to help me fix this problem would be greatly appreciated.

Also, my hostname is pbw.massinfluence.net and every so often when i open whm I recieve:

The server was unable to lookup an an A entry for its hostname (pbw.massinfluence.net). This is generally because the entry was never added. However this could also be the result of your nameserver(s) being down. If you would like to attempt to automaticlly add the entry, "click here'

then after clicking it says:

Found your hostname to be: pbw.massinfluence.net
Found your short hostname to be: pbw
Found your domain name to be: massinfluence.net
Found your main ip to be: 66.79.171.10
If this looks correct,

I add the entry.. IP=66.79.171.10 Add Complete

But next time I open the same box will popup. I'm kinda stuck and not sure what to do. If I need provide more info for you to properly help, just let me know.

Thanks in advance for any ideas you guys might be able to offer.

hmm.. I did nothing, except give it a few hours, and those subdomains magically decided to work. I just tried to make another http://subdomain.massinfluence.net and it gets page cannot be displayed as well. But it can be viewed at http://massinfluence.net/~subdomai/

Does anyone have an idea what i setup wrong to have it take time to work like this?

Also, I still get that hostname popup when logging onto whm.

Thanks
