I downloaded "The Lost And Damned" add on for GTA IV while it was reduced on the 23rd July 2011. It costed 400 microsoft points so i purchased 500 microsoft points, adding to my 200 spare microsoft points. So with my 700 microsoft points I tried to purchase "The Lost And Damned". It said that i couldn't purchase it so I waited for a little while and tried again. This time the marketplace took the 400 microsoft points off, but "The Lost And Damned" add on wasn't downloading. I then waited, but the download still wasn't downloading and i didn't have my full 700 microsoft points, i only had 300 (not enough to purchase it again).
Please help :(
