Rented movie that already started, times out and won't play

My husband and I rented a movie last night. We fell asleep watching it, so we wanted to finish it today (48 hour rental). However, the tv now states that we don't have access to that channel since it's not in our normal 'list' of channels. But how were were able to rent and watch it last night? There is no error message provided either, only the 844 number to call and subscribe to the channel. 

 Curious and wanting to finish the movie ...
