Same thing happened to me when I tuned in to watch Embryos On The Snow.

I had registered a couple days in advance and received my bidder # via email, but when I tried to watch it, the screen said that I needed to re-up my subscription (either $20 for a month or $50 for the year) I guess my subscription ran out. I don't think I will hand them any money. I will make my bids over the phone or not at all. They say it is because of the amount of kids tuning in and the bandwidth needed (all that costs money) and then the breeder or association putting on the sale doesn't have to pay the video feed fee. Well, Cattle In Motion charges $1.00 for a lifetime and does a fine job, so they have my business. Plus, they are broadcasting the National Western Stock Show's Livestock shows and supplying show orders. Great service!! You have my vote CATTLE IN MOTION!!!
BTW: I am not an employee of CIM only a satisfied customer.
