I tried again later several times and am afraid the rental period will expire and will not be able to watch the movie. The system also does not allow me to re-purchase the movie.

I've rentented a movie and would like to watch it. Consistently I receive the message "an error occured loading this contnt ...try again later". I've tried over a long period several times but always receive the same message. Also, I tried to re-purchase the movie but the system does not allow this. It just confirms "you have already rented this movie". any suggestions. Can't I just cancel the rental since I have not even fully streamed the movie/
