As stated in title, the solutions given on this forum have not worked and I am still booted from servers with the "Not Connected" reasoning. It usually happens at the end of a given round or as soon as I join the game. I have tried both versions to no avail. I also validate steam files after every crash and it says between 7-8 files are missing every time so far. Sometimes it does not happen and others it is every game. Any help would be greatly appreciated.

Hi, just to clarify, do you have issues connecting to game servers or does it throw you out during the game / while you're already in the room? If it's the latter then please make sure your internet connection is stable as that doesn't sound like an issue on our end.
