Flixster UV SD / HD download problems

[Pineapples101]

I've been having a bit of back and forth with a Flixster rep via email and I'm not getting anywhere with then... So Im hoping someone here might be able to help?

My problem...
Title: Lego Movie

I originally had the option for either a standard definition or a high definition download on my iPhone 4S. I chose standard definition, but later regretted my decision (as the quality was not great) and decided to delete the standard definition version off my iphone and download the high definition version to my iphone, I was able to delete the standard definition version, but now I don't get the option for high definition download - the flixster app just automatically re-downloads the standard definition version.

Is there any way to solve this?
Im using an iPhone 4S with the Flixster app.
