Ok I have the same problem downloaded Xinput1.3.dll and put in windows system folder & game folder & systemwow folder and get the xc7b error as well I have a 1 TB hdd new 4 gigs of ram jumped up my VM to 5000. And still have the xc7b error
I can't log on to any servers had a XINPUT1_3.dll files missing so I downloaded it and placed it in the game & windows folders.
But now I still can't log into game by launcher or the other Renegadex. My OS is Windows 7 64 bit
