Premiere Elements 15 Conforming A Clip Removes Audio

I have been trying to edit a clip in PE15 and all has been good, for the first minute, after a while of trying to find out what the problem is I Noticed that the problem I was facing was that whenever the video was conformed (progress bar in bottom right of screen) the audio would stop working. The audio clip still says that audio should be playing but I'm not hearing anything, I have checked to see if its my sound being off and simple things like that etc. but I cant seem to find a solution, anyone have any ideas?
