When I sign in and try to get the game started, I end up with an error message popping up saying "Version mismatch." Pops up before I reach the character selection screen. After it pops up, it just returns me to the login screen. I have no Idea what to do, please help.
Open your launcher, go to options; it's on the top. check a box for "Force verify" and "Patch via proxy". Setting your Proxy to either US or EU may help with the speed based on where you live or whichever is closer to you. Click ok and restart the launcher and try again. Enjoy!
