TVRage is down and has been for most part of the past 24h. No idea what is going on and if it'll ever be back.
If they're not back online within the next 24h, we may have to switch to TheTVDB.com or another source.
Let me know if you have any info about what is going on with TVRage or ideas for other data sources.
8th September Update: Episode summaries are now fetched from TheTVDB.com. Let me know if you notice issues with this. I'm working on getting the schedule data (probably temporarily) form TheTVDB as well.
