unable to open file from Real Player

susan123

I downloaded a movie using Bitcommit.  When I use Real Player to open the file, it says it has been removed.  But I did not remove the file.  It is there, but I can't open it.  I copied the file and saved it to another driver, it plays.  Do you know why?  I tried both version, Real Player 10 and 11.  I even tried VLC and it did not work.  Please advise.

I tried all source of players and it doesn't work.  I wonder if this has to do with Window Vista.  Could it be the computer and not the player?  I was able to copy the file to a flash drive and play it, No problem, I just have problem playing the original file on the desk top.
