I have an xbox but have only ever used it once.

(Maybe i should sell it!! but that's not the point ..)

Today I turned it on for the second time, it asked to update so i said ok.

But now i can't sign in to XBOX live. I used to be able to coz i had downloaded many demos and now i want to see more demos to download.

But everytime i click sign in to xbox live the cursor goes round and round, and makes a buzz, and it buzzes again, and does not sign in.

No error messages!!!
