I'm trying to buy a Windows Marketplace, on my phone, I had the opportunity to download and install the trial, when I decided I was satisfied with the application proceeded to purchase the application, when I selected to buy, I went to the proof screen payment and said my credit card, then select buy again to confirm the payment and after a brief think that returns the message "Can not get this information at this time. Back in a while." little time has been 3 days now, FYI I tried this again on 3G and Wireless. Today I try to buy all the way during the Zune. When I click to buy the Zune goes to the proof page and shows my credit card and press the button to buy back after a brief think it shows an error that says "Web Help an unknown error." So please help me and give me some solution.
