WMC Suddenly not connecting / downloading guide. "Guidedownload error" It has been working with EPG123 perfectly, but has just (in last week) been unable to update. Internet is working perfectly. I've checked the clock time, I've checked the Update Service is running, I've completely re-run the WMC set-up, wiping out all my custom channels! I'm away from home for the next few days, but if anyone could offer a checklist for when I get home I'd really appreciate it.
