Like I said above, I would have thought that sufficient time had passed for your domains DNS info to have fully propagated by now. If www doesn't begin resolving for you within a couple of days, I would suggest lodging a support request detailing the problem, there may have been a 'glitch' in the system somewhere.
Another thing that comes to mind, make sure you clear any DNS cache that might be active. If you are using Windows, enter the following command at the command prompt to clear the Windows DNS cache.
