Adobe Premier Elements help needed

[Mr Mindstorms]

Hello all, I'm very new to Adobe Premier elements and I'm just attempting to use to make a quick edit with a video, it seems however that I've run into a problem.

 

I've got an MP4 of Shrek which I need to make a quick edit to (don't ask), and when inserted into the application (via either means of dragging/dropping or searching and inserting the file) the video works fine, but I only seem to have the background audio, by that I mean that I can hear the instrumental but no vocals from any of the characters.

 

At first this seems like a headphones problem, where it's only coming through one of the channels, however everything in the movie works fine when viewed in any other software (films and tv, windows media player, etc).

 

So is there any clear quick fix for this? I'm very new so assume I know nothing, be gentle.

:)

Just run it through a video converter like handbreak and wreck the audio into one channel
