Whenever I try and open Cubase 8 without the eLicenser USB plugged in, it says no registration. Do I have to keep that plugged in all the time? I’m not understanding the eLicencer and it’s giving me an eHeadache. 
Hey. You have to have the eLicenser plugged in when you open Cubase in order for the program to work.
Can I pull it out after its loaded?
No. The program will freeze up if you do.
