Having trouble accesing my notifications/even opening and using CATIA

I've submitted a form to take part in 'project of the year' ( which gives students a free liscense) and nothing worked after I received my liscense. First is that I can't even acces my notifications about this program.Then I helped myself out and downloaded 3Dexperience local app and still find that I could't get to use it smoothly, it says failed connecting to server.Email verified. I still don't know why the mess....That's why I'm here for somebody to help out.
