There's a new client out. You can dl that in the Announcement's section.
Once you've dled the new client. When that's finished, don't click on it or do anything to it. Instead try to patch the game through a file called "Alternative_Sakray" first. Once that's done, DO NOT press "Start Game." Instead, press "Exit," then click on "AnthemPatch" (I think it's called that, I can't check atm). Once that's done patching, try logging ingame.
It's always a good idea to use the Alternative Sakray program to patch right before using the regular Anthem Patch. This is especially true when the server gets a big update.
