When I try to create a windows store program in Visual Studio 2012, I was prompt to install the developer license, but VS2012 failed to get the license all the time, please see the picture below.

I closed this dialog and try it againd from Project-Store-Acquire Developer License, but still get the same error. 
I google this for a while and found a page on MSDN said there is a command mode, I try that, get the same error, see below picture.

I upgrade my Windows 8 from Windows 7 several days ago, and it was actived.

I didn't use any proxy for my internet connection, I can not build my windows store prgram without the license. any work around for this?
