Has anyone else experienced this? And if so, how did you overcome the problem.

I am running MM v2.36. Suddenly, my BDP-2 won't automatically go to the next song, but keeps playing the same cut over and over again. If I click on another song, it will play the new song. I have tried undoing the repeat icon and the random icon. I have rebooted, done the update (several times!), cleared the cache, reset the DB and still the issue persists. The only thing that I have not yet tried is to do a factory reset (absolutely last step). Does anyone have any suggestions?
Thanks in advance.
