Mobile Air Mouse - ATV 4.5

Since updating to ATV 4.5 I’m not able to activate the “Mobile Air Mouse” in the Menu “Maintenance - Manage Plugins” - any help?

I also do not find the “Mobile Air Mouse” in the Menu “Maintenance - Install Extras”. Since I updated to ATV 4.5 my Mobile Air Mouse Application is still installed but only selectable through “nitoTV - Applications”. If I start the Mobile Mouse over “NitoTV - Applications” I can connect over my IPad but since I have to leave the application (to start for example xbmc) the connection is lost immediatly. In prior versions of ATV I was able to activate the Mobile Mouse trough “Maintenance - Manage plugins” and the connection from my IPad worked fine using for example xbmc?

Any ideas?

Thanks in advance.
