iTunes force quits when watching a TV show

I recently purchased a season of a TV show from iTunes when I go to download the show it won't fully download or it will stop downloading and when I go to actually stream the episode iTunes immediately force quits and throws me out and pops up with a warning telling me to "reopen" "report problem" or "close". I have everything updated on my MacBook and have deleted and redownloaded iTunes. the shows play on my iPhone and on other peoples MacBooks just not mine. how do I fix this problem?
