I've contacted them on Twitter:
http://www.twitter.com/eurosportuktv and they picked up on my missives about the Eurosport Player being on the fritz.
But year, 15 minutes late to the party is pretty shabby. Glad I'm only subscribing to them for the duration of this month to watch Le Mans, otherwise I'd have no hair left, pulling it out in frustration over their complete failure in keeping to their own schedule.
