How can I get Adobe Premiere Pro to work on my NVIDIA graphics card?

I have a HP Envy dv6-7250ca laptop running Windows 8 with an Intel Core i7 processor and a NVIDIA GeForce GT 630m 2GB graphics card. I'm using Adobe Premiere Pro CS6, and every time I try to run the program through my NVIDIA card, the program monitor remains black and I can't see any video. However, it works fine if I run it on the regular Intel card. The only problem is that I can't play videos without having to render them first, and the main reason why I bought this laptop is because it has a Core i7 processor an an NVIDIA graphics card.

Is there something I'm doing wrong? Or is this graphics card still too weak to be able to edit 1080p video without having to render so the playback won't freeze or be very choppy?
