Liberty Square Audio Guide - Video Preview cannot be played on this iPhone

I was wondering if anybody has run into this issue. I like to have the previews on my iPhone 3GS to watch every once in a while. But when I try to download the Libery Square Audio Guide, I receive "Video preview of the Liberty Square Audio Guide cannot be played on this iPhone".

Thanks!

Had that issue with my itouch. I emailed Lou and he gave me instructions now i can't find them. I would email Lou@wdwradio.com
