Whatever that file is it did something bad to the client, with that file in the game directory it prevents me from launching the client and initiates a bunch of errors. Without it the client launches.
As for enabling videobackbuffer, I did so, but the problem still persists.
The game disconnects as soon as the game starts every time to which I can't even deploy my MCV.
(Edit) So now I'm having the same issue with Ra95. I tried disabling Windows firewall, but still nothing.
