Hyperdeck shuttle 2 - can't import Avid DNxHD QT file into Premiere Pro CS5.5

Hi,

I've been searching forums but none of the solutions have worked for me:

When I try to import a DNxHD quicktime file produced by my hyperdeck shuttle 2 into premiere pro CS5.5 I get the following message:

"Unsupported format or damaged file"

I have version 3.0 firmware for shuttle. I just installed the latest Avid QT codecs (2.3.7).

The footage opens fine in Final Cut 7 and Quicktime on the same machine.

Specs are:

Adobe Premiere Pro CS5.5

Mac OS 10.6.8
MacPro4,1
Quad-Core Intel Xeon
2.66 GHz
Memory 16 GB

Thanks!

Josh
