I already read the FAQ'S and found nothing about this, so, when i press the (R) key to configue the drone controlls, it opens up a menu, when i try to configure the keys, it says its causing script errors, and tells me to check the console!

I will leave screenshots so you understand the error, if someone can help me, please do!
