I bought a pre-modded system a couple months ago that has worked fine up until last night. I had XBMC installed as the dashboard. Last night when I turned the system on it went straight into the original Xbox dash. Turning the system on with the eject button does not bring me into the XeniumOS menu like it's supposed to. Anybody have any suggestions - or need more information from me? Thanks!

sounds like the D0

Agreed.
