your file somehow (strange) is in the wrong format. The file type is of Real Player which will not be recognized by Quicktime. The reason I say strange is because Soundjam doesn't allow the option to save as a Real Player document. You may note however that warez and Mp3 sites practice changing document file types often in order hide illegal downloads in formats such as Real Player, JPG, BMP, etc.
So, if you accidently downloaded a file from one of these would be sites ,try playing your file with "SoundApp", that should put a fix on an incorrect file type, then play it with Quicktime.
