I can't both open and activate Harmony

Today I tried to open Harmony, but it just stuck on the opening. This problem is still there even though I reinstalled it many time. And when I tried to activate it by licking the license I’ve already got, it said that I couldn’t activate and there was an “error code 0”. I don’t know what that mean.
