Resolve 9 difficulty-help is needed

I have newly purchased and installed Resolve 9.
The program boots up fine. However, I receive a warning that "Your current hardware configuration is not able to support maximum realtime performance."

After booting up and starting a project, I cannot load any quicktime files. I receive an error stating:
"Error occurred while trying to decode frame from clip..... using QTDecoder."

If I load another type of clip, say a Red Epic shot, that loads, but then my Power Window will not appear in the Master Color Viewer.

My platform is a Mac Pro, quad-core intel, dual processors with 14GB of RAM. The OS is Lion and my graphics card is a NVIDIA GeForce 8800GT. I also have a RedRocket installed. I believe all of my drivers are up to date.

I am in need of help to get this program up and running. Any insight is appreciated.

Thanks.

Also, on the "Deliver" screen, my keyboard will not work. Which is important when trying to name files and such

Thanks.

I believe the issue is your GPU. It's really underpowered for the needs of Resolve.

Check out the config guide for more details.
