I was playing Black Ops then i wanted to make another account. When i went to sign into it it told me a new update available, 3.56. Then "error 80710723, update unable to complete" came up so i reset my internet settings five time, and restarted the router, and it still occurred. Every time i retry it gets a little further in the total percent complete. If anyone else is having or had this problem then give me a answer please. If you have no clue then should i just contact technical support?
