I have done that couple of times, it did not work. I finally was able to make it to work by creating another profile on my Mac and then doing a fresh install on that.
I have to say the support for this is "wanting", there is a very hard resistance to escalate customer issues and the uncanny way to repeat the same steps that the customer is saying is "not working". For a company that touted customer empathy, the behavior by the support teams is really not upto the standard.
