OH FFF I JUST remembered this.
Okay. here's an issue that a friend of mine had had before.
Say your username is 'Kaylah', just like that. If you have logged on, you might have typed 'kaylah' into the loggin box. While this will allow you to loggin, this will also affect your preset when you export, making it 'kaylah' - thus not the exact same (in capitalization) as your username.
Yes, the presets ARE case sensitive! They will not work if your username is not the exact capitalization as it was when you registered!
So go ingame, type the correct capitalization into the loggin box, go to preset maker, and re-export it. This will hopefully export the preset correctly, and once you send it to your pals, it should work.
