I've found the problem. It existed two instance of the Unity EventSystem in the scene.
One getting attached when you add the UFE script to the main camera and the other one getting added to the UI canvas in the Awake() methode of the UFE script.

Topic: [SOLVED] Control Freak 2 Problems (1 replies, posted in UFE 1 (Deprecated))
Hey guys,
I'm started a new project with UFE and Control Freak 2 for my mobile touch controls. Everything is working fine until I'm restarting Unity. After the restart the touch controls not working anymore (not in editor nor on a mobile device).
Anyone of you know this problem an can help. I already spent a couple of hours to fix this issue...
Setup:
Unity 5.3
UFE 1.7.2
CF 2
Repro:
1) Create an empty project
2) Import UFE
3) Import CF2
4) Install the CF2
5) Install the CF2 plugin for UFE
6) Add the UFE script to the main camera
7) Apply the UFE config to the UFE script at the cam
8) Switch the input options to CF2 in the UFE config
9) Add one of the 3rd party assets (of CF2) as sontrol prefab in the UFE config
10) Start a fight
--> Everything is working fine. You can use the touch controls with the mouse in the editor.
--> Restart Unity and start a fight again. try to use the touch controls again with the mouse. NOTHING happen 
Hopefully somebody can help me.
Best Regards
