Thank you guys, I can hear everything fine, but I've got a problem with energy balls (again).
While trying to complete my level, I noticed that once the energy ball reached successfully the ball catcher, another ball is launched by the ball launcher and I don't understand why to be honest. How to be sure that the launcher stop to fire balls when one has already reached the right ball catcher ? Any ideas ?

Okay, to start with, to change anything in an output, click on it first in the list. This is why you couldnt type anything in, you hadnt selected the output. ( or, on second thoguhts it could be because you were trying to send it from a func_instance.)
Secondly, dont have the output from the func_instance, create a new entity, a logic_relay and name it @Ballcatcher_Relay. This is where you should send your outputs from.
Thirdly, here is what it should look like:

Fourthly, you shuld look at doing some basic tutorials on i/o, there are plenty out there.
Lastly, good luck!

Read this. And when you have read that, make this, OnTrigger > [Launcher instance name] > Disable

This works like a charm, thank you but now I got another question (not about energy balls at all).
I want to bring back the sound effects of the "floor_button pressing" and a "door opening" from Portal into my Portal 2 level. To be honest I don't like these sound from Portal 2 and I think those from P1 were just awesome. Do you know if I can achieve this and replace the current sound effects for the old ones from Portal ?

Try this: mapping-help/adding-custom-sounds-t2739.html
I think this is what you're talking about. You'll have to extract the original sounds from Portal 1 before you can use them, though. However, I'm surprised that the button sounds from Portal 1 aren't in Portal 2, as there are a lot of HL2 sounds in Portal 2.
