I cant join any of the servers.. dont know if im banned or something. HELP

[Maaaax]

I was playing a couple of days ago and everything was okey..
i had some friends over that watched me play and i went for a shower later.
i closed the game and let them play assetto corsa whilst i was in the shower.
i told the m to not play lfs since they always want to run from police and drift all the time so i closed it..
im just curious to know if im banned or something because i cant seem to join anymore..
they know how to start the game and all but i asked them if they had done something but they said no.

i know about the (its your account, your responsibility and all..
if anyone could check if im banned that would be great
