Cannot Download Windows 8 from DreamSpark Premium [Update: Fixed]

I know this isn't the best place to post this kind of issues but I can't help my self.

The thing is I am getting an error when I try to add Windows 8 Professional 64-bit to my shopping cart. A picture is worth a thousand words. So here is a screenshot.

Notice that I have previously downloaded Consumer Preview from DreamSpark. I'm assuming the problem is occurring because of this.

Anyone else experiencing this issue? Is there any workaround for this? Please let me know in the comment section.

Update: Thanks guys. The problem has been sorted out. I contacted DreamSpark support and they have fixed the problem.
