I remember that it happened while I was searching for a requested song. Since I have several versions of songs I don't use the number that the catalog has but instead I tell my customer the different brands that I have. I think that I selected the requested song, now Hoster takes a while to upload to the playlist, the current song ended at that very moment and Hoster stopped responding. I think that it can not handle to finish a song and start the next one at the same time it loads a request to the playlist.

. Something that will happen to every one of us Karaoke Hosts.
Just as a comment that will lead to another thread, one of the restaurant where I present my show ask me to switch back to Hoster 3.21. At one moment, last night, I restarted a song 5 times, syncronicity issues, with no luck. I had to go back to Hoster 3 included in version 4 which has some issues itself.
I will have to uninstall because people are starting to tell me that there are too many mistakes after the upgrade.
Sorry, MTU, I don't mean to disrespect your honest work but Hoster is not working as it used to work.
