Yeah, it's rather annoying that they didn't allow it straight away, I think it was some kind of argument that consisted of Activision saying that "They will make sure that only GH products will work with GH." I think they even counter-updated it when the game came out as the guitar did work for a short time.
Everything seems OK now though. Couldn't you sign into LIVE on a friends console and update it onto your storage device or something?
Don't worry- I read the post
Thanks! That makes a lot more sence now. I thought my game was glitched or I was recieving false information. I guess I will have to use my wired controller to play Guitar Hero Aerosmith then. I wish I had LIVE access
