Hoster 5.40.01 Shutting down

[TomboxUS]

Has anyone else had this problem with Hoster 5.40.01?
It has happened to me four different times a song will play then a message comes up saying The parameter is incorrect!
I have to go to task manager to shut down Hoster and then restart the program. The song that has just played will still be there when it restarts, I delete it then go on to the next song without any problems. It happens once a night it is not the same song each time. I have no idea what is going on...
