This is usually a symptom of a general performance...
I can't start an already created game, there are errors in the console:
sound system low level ;
audio device starved at 441 samples ;
Changing sound settings such as input and output devices helped several times, but then it stopped.
I have not received any temporary bans.
Updating the video...
