Error code 84

now, besides the error on the SIPT platform and error VAN68… I have error VAN 84, is nothing going to be done about this Vanguard? or can someone help me fix it?

It’s impossible to play, the client doesn’t load, infinite loop on everything and when it finally gets in it gives error VAN 84, I’ve already uninstalled and installed again, I’ve already formatted the PC, I’ve already restarted the modem about 10 times, I simply can’t play.
