I recently installed CS5.5 onto my son's new Windows 8 computer (and made sure to install of the the undates). Everything seemed to work fine until I created a new project in Premiere Pro and tried to drag a video file into the timeline. I was able to select the video track for the video portion, but the audio was placed into Audio 5 and would not let us move it to any of the other audio tracks. Unlinking it from the video didn't help, nor was I able to find anything else that could be causing it. Obviously, this renders Premiere unusable. Does anyone have a fix for this?
