have just bought oblivion today along with the shivering isles expansion disc.have installed both discs to the hd (and updated when asked to from the disc) but when i load the game and it says loading content,nothing happens? i remember this happening when i got the goty edition a few years ago (but forgotten how i solved the issue) i had recently updated the 360 also (using a usb stick/as no phone line for xbox live)any help to resolve this would be much appreciated
