Error trying to save changes to my new domain name

Unable to save changes  in Custom Website Domain:
changing from burwoodTm.org.au 
to
Burwoodtm.au
I get a jave script error asking me to contact support 
I need to change my website domain to Burwoodtm.au



Club 6865,  VPE Burwood 6865

The DNS for the new domain must be configured before attempting to add it to your site admin console.

Your MX records are not correct. FTH email will not work with Burwoodtm.au

 I had my domain provider add the records for me.
I believe I need to wait 24 hours for the changes to work.
Then I can change the address in the FYH admin console, are there any other steps?

You should be able to add the the Admin panel now.

 

I have tried a few times on different machines the same error apears, do I have to change something in club central?
