Your license and its corresponding hardcoded keys in src are for your private use. If you're going to sell your emulator, you'll have to remove your license, which means you won't have access to utilities like LGP, packet encryption, etc.
If you sell the license to increase the value of your mediocre emulator, it's normal for it to be removed.
Why aren't you ashamed to come and cry because they've taken away a service that you were trafficking illegally?
The ones who should be complaining are the clients you scammed with your mediocre courses and information.
