We have an Xbox 360 - don't use Xbox live, but when my kids try to play a game, it's saying there is a required update. We hit 'yes' to download and get an error, can't connect. Went through all steps in system network settings, shows Network: connected, Internet: connected, then pops up 'Update Required' won't be able to connect to xbox live until you take the update--click 'yes' to apply. Fails. Gives Status Code: 4180-0000-0080-0300-8007-045D Vicious circle. Please help--we DON'T need xbox live--just want to play the games we already have that were working fine before!
