"NullReferenceExecption: Object reference not set to an instance of an object" error when using array of own made class objects.

So I want to do an interface in which the user could create his profiles, which would be saved in text file. Profile consists of name and keybinds. Everything seems to work if I use only a single class Profile object, but there should be ability to add more than one profile, so I want to have array of class Profile objects and I get the following error: "NullReferenceException: Object reference not set to an instance of an object Profiles.Update () (at Assets/Profiles.js:138)"
