Receiving this upon start?
Firstly, be sure you are not on Windows 7. This is the main cause for this error. Cyber no longer supports Windows 7 and you will need to either update or run on a server.
Secondly, you can try unbinding from the discord, rebinding to the same discord, and launching Cyber again.
If that isn't the case, back up and delete C:\Users\<USERNAME>\AppData\Roaming\CyberAIO then try running again. To navigate to this location, press Windows Key + R then paste that location into there with your username.
If your problem still persists, please create a support ticket or post in #help in the Discord.
