Greetings, @dakyd23. First, we'd recommend verifying that you have the most current version of the client installed. The client version should be 220.127.116.113227, and is shown in the bottom-left corner of the login screen. If not, try these steps:
Close both the game and the launcher
Open the game installation directory
Open the folder named "Launcher"
Inside the "Launcher" folder, there is a folder named "ProgramData"
Rename the "ProgramData" folder to "ProgramDataBackup"
