Error on Flixel and Openfl classes

[Katastroph]

Hello guys !

I've just upgraded my version of Flixel (2.0.0-alpha.3 -> 3.3.4) and Openfl (1.0.6 -> 2.0.0).
Now compiling give me these errors :

The "source/ProjectClass." parts are errors from my code, although I do not understand why : I have a super in the constructor but it does not accept the FlxState I pass in parameter.

If you could give me a hand that would be great !

This is happening because you are using an outdated version of Haxe. Get the latest version here.

It works, thank you very much!
