Mediacom is an account people are using to watch sports, getting the same error. There's nothing you can do on your end. You've got to contact the provider and get them to bang around under the hood.Yes I was! I don't know what a mediacom account is though. Is there something wrong with my computer or is it with the Lifetime site? I signed up for a Lifetime account in attempt to watch Big Driver. They wanted a cable provider and I entered that (my internet provider is a cable company). It looked like they accepted all my info-but I've received this message a half dozen times trying to view the movie. The clips and everything else play though.
