Cubase 9 artist crash on launch

Description: Cubae 9 artist installed, elicense and dongle installed and activated and registered without a single problem. There’s the problem, every time I launch Cubase as director select any project, a message box asks if I want to register with 3 options. Since I already registered I clicked “Already Registered”. I then get a serious error messages and have to use Task Manger to close the crashed Cubase. I found thoug, that if I select “Register” when Cubase launches, it goes to your registry web site where my info is already populated, press ok, thanks me for registering, and returns to Cubase starts the project and Cubase runs fine. I have to do every single time I launch Cubase or it will crash. For info, I have Bitdefinder 2017 antivirus.
