Hello
Since you didn't erase that Dropbox link, I assumed it was ok for me to download the clip to see how my system handled it.
So I went ahead and downloaded it out of curiosity and I can confirm Mark's findings: Premiere Pro CC 2014 imports and plays back that particular file just fine.
I am running a Windows 8.1 machine with dual 8 core Xeons, Quadro 5000, 64 GB of RAM, SSDs in RAID array.
So I tend to concur with Mark who wrote above: "If you have any codecs installed, perhaps one of them is actually interfering with Premiere reading your clips."
