I downloaded the Resurrection Pack 4 for my Call of Duty Black Ops game and all of the maps work fine except the moon map. It starts to download, but then just freezes, no error message. So I took the advice off this site to delete the add on, clear cashe and download again, which I have tried many times now with the same result, no moon. I have since purchased a 250 internal hard drive for my 4 G Slim thinking I might not have enough memory, but this didn't work either. Someone told me to purchase a USB flash rive and try downloading and playing it from there, but still no moon. Could this be my wireless broadband isn't wide fast enough or too much of it is being taken up through other computers in the household? HELP!!!!!
