My BGE Message actuator does not work although others are working I'm having a really big problem with my message actuator. I need you to help me find the root of the problem.
This is the image of the object's logic that sends the message below:

And this is the image of the object's logic that receives the message:

Although others are working (which shown green), message shown in red doesn't work and i don't know why?
I tried most of things but it didn't help.
*I'm sending messages between scenes.
*I tried to change the name of the object and didn't work.
*In my previous save files, it was working and this file goes the same way.
*I checked other discussions but nothing would help
UPDATE: Problem occurs from mouse clicks. When i set for keyboard press it works but mouse click (mouse over + left button) does not work. Does anyone know why not?
