PLAYING .WAM FILES

I HAVE UPLOADED .WAM FILES, BUT EXPRESS SCRIBE WON'T PLAY THEM.

I HAVE MARKED THE .WAX AREA, SO THAT EXPRESS SCRIBE WILL PLAY THEM. BUT THEY STILL WON'T PLAY.

WHAT DO I NEED TO DO TO BE ABLE TO PLAY THEM?

I NEED TO TRANSCRIBE THE FILES REAL SOON.

I WOULD APPRECIATE ANY HELP ANYONE CAN GIVE.

What is the file size of these files? Are they actual audio files, or placeholders/shortcuts to audio contained on the internet?
