So I've tried to update guide listings. The pop up tells me to check system tray icon. I did, and it state that there was an error getting guide data. I re-run download while on desktop, it showed :downloading tv guide data, reached 100%, then it stated processing tvguide data and again reached 100%. However no TV guide data was updated in the Media Center. Once I got back to desktop, system tray icon stated error getting tv guide data and would try again at 3am.
I'm not sure whats going on. It seems that it is able to connect and download data from servers, but has problem actually processing data.
