Okay so when I make a music utility I tell my friend the pass but she tells me everyone frezzes when she clicks submit. I don't understand why so I think it may be a bug because 2 of my friends couldn't go to my utility

I tried without password but it still frozes

I'm one of those friends. All the mice just freeze where there are. When the time goes 0;00 no map changed...

Anyone some help...?

Sounds like a connection issue to me. It's possible that either you or your friend was disconnected from one or more "satellite" servers. These satellites all host a bunch of rooms and communicate to the main server. When disconnected from these auxiliary servers you will have this kind of connection problem. Relogging should fix it.
