Hello, I'm sure this problem had been addressed somewhere before in this forum, unfortunately I'm dumb and I can't really figure out how to fix so I hope I'll get some help on here.
I've downloaded the game fresh out of the website, also downloaded ZClient. I finished installing the game + DLCs, I extracted Client.zip and replaced the files inside the game folder. I ran ZClient, logged in, then started running the launcher (also downloaded from the forums) and I clicked on joining a server but the error came up. I've followed the instructions on FAQ but I'm unsure if I had done something wrong (My windows defender was also off during the installation of the game and when I ran ZClient). Currently I'm reinstalling the game again for the fourth time and I'm afraid that I will run into the same error again, someone please help me, I sincerely appericate your help.
