Just a word of advice, it is against Upwork terms to try and create multiple accounts.
As you said that you had an account previously, so one of the reasons for failure could be it. You may have luck trying to get the previous account activated again.
I have been trying to get a few of my friends to join upwork and none profiles were approved, so I am not sure what is the right way to go as well. They were professionals, and had a few years of experience to show for, but they got generic message of rejection, and they were very discouraged.
