I Can't Delete a Video File.

Yesterday i got A Redeem Code for a Simpsons' Halloween Episode, and i used it on My iPod Touch 5G, and then i stopped the download from the Videos App/Page and then i started to sync my ipod, and when i went to the Videos there is the Episode but i can't delete it o watch it, it says "the video can't load" and when i try to delete from iTunes it doesn't appear there, what can i do,
I Don't want to Delete all my Stuff

Thank You.
