if someone is having problems with ELS not working like it appened to me (lights didn't work at all, there was just the bipping when you change the lights)
try checking for updates on windows configuration tab (Win 10) I updated my PC and ELS started working normally as usual.
this worked for me. update windows 10 if your ELS isn't working.
