Man with the Iron Fists HD Download

So.. I purchased the Blu-ray, DVD, digital combo pack the other day... I downloaded the movie from itunes using the redemption code... unfortunately it downloaded only the HD version and I can't seem to figure out a way to download the standard version without having to pay for it... the HD version comes up with the error message,: "To play "The Man With the Iron Fists" in HD, your computer must have Windows 7 and a built-in display or a display that supports HDCP.

Strangely enough I also own the expendables 2 and skyfall (which also have HD editions) and they play fine enough... can I get some help with this?

Thanks!
