Endless loading

I downloaded the game on steam and the game just won't start. Just endless loading and I can't even get into the lobby. On the Internet, the only way is to plug an Internet flash drive, but I have a wire. At what the error does not even get out. It just keeps loading. I tried to pull out the wire and an error immediately flew out, and after the wire returned, the download was eternal again. Internet works fine, other games work without lags.
