MR816 with Sony Acid...Windows 8 Issue?

I am trying to set up my new computer (Win 8 64bit) to use my MR816 with Sony Acid. I installed the newest MR Tools without an issue. The interface is set to be the audio device. However, when I try to record, I do not have access to all of the MR816 inputs. Sony Acid does not allow me to select any other channels/inputs other than input 1 (which is in stereo). Any ideas on how to fix this?

To clarify, I can only record the master channel. I am not able to select an individual channel from the mr 816 to record from.
