When I switch on my Xbox console I am greeted with a message which says that I require an update. When I confirm that I want the update the system tells me that I need 190mb free space for the update and that my system does not have enough space. This is not true as I have a 250gb Xbox 360e console with about 200gb free space. I am then unable to access Xbox Live. I can get round this if I switch the console on and off. The amount of times that I have to switch the console on and off in order to access Xbox Live and my profile varies every time. I have deleted the system cache and I have also deleted and then downloaded my profile. None of these has solved the issue. Does anyone have any ideas? I am really losing my rag with it. Thanks in advance.
