If you are getting this error message, it means a Badlion Client file is missing or corrupted. It's usually caused by the following:
- Antivirus is interfering with Badlion Client.
- Badlion Client is not run from its directory but through software (e.g. Razer Cortex).
Doing the following should solve the issue:
- Disable your antivirus and then reinstall Badlion Client.
- Make sure to run Badlion Client directly from its directory, and not through any software.
