I went to use my 360 this evening, and as soon as it powered on and logged in, it froze. Restarted it, and the same happened again. Zomoniac off of ugvm reported similar problems yesterday.

After some faffing around, I tried disconnecting my network cable and starting the 360 up again - and this worked. Plug in the cable, connect to Live, and it freezes. Naturally, and following the problems with Live all week, I assumed that it was Microsoft’s servers up the spout.

Then a post on rllmuk linked here. Turns out than an incomplete download of the new Pro Evolution Soccer game is to blame. And what was I part way through downloading when I switched my 360 off last night? Exactly.

So I disconnected the 360 from the network once more, started it up, deleted the incomplete demo download, and reconnected to Xbox Live. The result? It works once more! Phew!
