So you're applying for a second charge card - not a change from the Green to the PRG? A complete second application?
If so, I think your odds are not good at getting the PRG. Amex generally doesn't like people to open the second account before the first has some history. Given that you had to call the recon line for the Green, I don't think you'll get any special consideration.
Edit: I hope you didn't make that decision partly on a misunderstanding of my advice from yesterday. You should have applied for the card you wanted and, if you were declined for that, tried to get a 'compromise' card from the same credit pull.
Given what you had done by that point, I suggested you should call and talk to a person and try to change the Green to a Gold before the account became activated or, failing that, to build up a history for a few months with the Green and then apply for the Gold - not to apply for a completely separate, second Amex 48 hours after the first one was approved on recon.
I would talk to a human being there soon, before the computer just assumes you're trying to open as much credit as you can get away with and are a high risk for even the Green.
Did they pull your credit once or twice, for applications 48 hours apart?
