Logging in via launcher won't start the game, shows error message.

[Argronok0]

So I have the game digitally thanks to an acquaintance that gave me a copy and I assure you it was a good copy of the game.

But so far after having followed the instructions to install it, when I try to log in via the Launcher, I get this error message:



I have been on the Discord servers asking for help and the suggestions they gave me to resolve this issue has not worked for me.

If anyone here can tell me what's the specific issue that the error message is showcasing please tell me, its been the same error message after all attempts I've done to resolve it.
