The UUID ban is a computer ban, you can bypass this by creating a new user on your PC/Laptop and download elkoy again. This doesn't always work though, you can always try splitting your C drive into 2 parts, that works in most cases aswell. The MAC ban you can easily evade by downloading a program named ''Tmac'' it will change your MAC adress to a random one, the adress will be reset the next time you re-start your device. If you experience any problems following these steps, feel free to shoot me a pm and I'll assist you.
