Hey there. When i try to connect "any" room in multiplayer, new screen comes out and says "not connected" and "click to select player" what is going on?

It's your internet connection/modem, or your firewalls. Try turning off your firewalls and then go to multiplayer in toribash.

i've just played toribash 1 hour ago. and i was playing for 2 days.. it isnt about firewall or something.

Well did you check it? Because thats usually the case with this problem..

i checked it.. now another problem... i can't connect to beginner servers.... now im in a ultimate judo server.

cant connect blackbelt judo too...

you can connect to servers which are at your level, one below or one higher.

Allow me to correct you on this. You can join all servers but blackbelt and ultimate if you're brown belt or less. If you're blackbelt, you can join blackbelt servers, not semi-pro or lower. If you're third dan or above, you can join ultimate and blackbelt. -Aslask

What Aslask stated and also any private room that does not have a set limit by the room op. (not all private room allow random people)

Edit: I guess he did say that. (a bit more indirectly)
