[Pr3datoR]

Good evening! I used to play a lot years ago, but nowdays I dont have a lot of time for the game :/ So, in the past few days i wanted to connect to the "TWC No Download" server, but it writes i got permanent ban, but it can't be, because i never got in game... my friend who plays every day said to refresh the network card, but it didnt help.. Somebody can help me, what could be the problem? My name in game is Pr3datoR (all characters wrote with orange color) Here is the message i get:
