Sorry if this has been posted before, I've searched on various forums and have had mixed results from years of this similar problem arising on XP and Vista as well. My Media Center no longer updates the program guide, making media center essentially useless. I've tried re-setting it like others suggested, but now it gets stuck at "Downloading TV Setup Data". Everytime I try to access the program guide, it pops up a message saying my list is expired and needs to be updated, but it never actually updates. My internet connection is fine, the system is fine. Nothing has changed to potentially cause this conflict to arise. Is this a problem Microsoft has addressed or? Any help on fixing this would be appreciated, as I rely on MC to act as a DVR.
