I cant watch a movie a watched in the past that...

Hello,

I need help please. I purchased a movie from Itunes two months ago. I watched the movie at that time. Tonight I attempted to watch the movie, it began to play then a message popped up "This movie can be played only on displays that support HDCP (High bandwidth Digital Content Protector" I dont understand why this popped up. Any suggestions?
