The latest update has completely ****ed over my console. The whole system is slow and even unresponsive at times. When I try to connect to xbox live it either won't let me or randomly disconnects after I get on. I can't sent party, chat, or game invites to my friends, and their player cards are blank except for their names and online status. When I accept my friends' invites to join a party or chat I can hear them talking to me, but they can't hear anything I say -- and I get disconnected from the chat about 10-15 seconds later.
Is anyone else having these problems? Does anyone have a fix?
How can I uninstall today's update and redownload it?
