Skyrim Xbox 360 issues

[Computing34]

Hi forum, I am having some trouble with playing skyrim on my xbox 360. I got the game on the xbox live marketplace, downloaded it to a USB flash drive (my hdd didn't have enough space), and have been playing it ever since for about a year. I haven't played it in awhile and decided to boot it up yesterday. The game wouldn't start and a prompt came up saying that it couldn't start the game and that I should try deleting the file and redownloading it. I tried this 4-5 times, but the same thing occurred. Some of the times it would just randomly stop downloading at 40,60,70%. I read another forum and it said to delete the cache and redownload again, which I did, and it still didn't work. Does anyone know how to help? Thanks

@vinyldash303 thanks, I didn't know this forum had a console section!
