Arcam FMJ UDP411 control issues

Good afternoon,

has as anyone had issues with their UDP411 not playing discs?  Like, put the disc in the tray, make sure it’s centered, press the close button, tray closes, display says “loading” then “sacd” then “open”.  The tray opens, and I stare in disbelief.  Try another sacd, same results.  Try a redbook cd, sometimes the tray opens, sometimes it recognizes it as a cd, but will not play if the play button is pressed on either the player itself or the remote.  Several power up and down sequences, similar results.  Finally got it to play a sacd, just kept trying until it worked.  Similar situation with dvd discs.  Is this a firmware issue?  
Any advice is appreciated,thanks

Dave
