The authentication code necessary to be recognized as donator is based on your PC's hardware. This means that if you replace hardware parts of hardware-based settings, it may change your authentication code/key.
In case you really need to replace a hardware piece or change a setting, let me know via my contact methods in the About tab of JDuel Links Bot and I'll replace your old key with your new one.
Please note that re-installing your system (Windows) will generally not change your authentication code so go ahead and reformat. In case your authentication code still changed, let me know and I'll assist you in fixing it.
