This is the screen I got when I tried to log in with my s.a.slump@student.utwente.nl email. Logging in with my s2361868 email doesn't work as well. What should I do?
Before you can use s.a.slump@student.utwente.nl you must register. I see you did this, but registered with username "Saskia Slump" so you must use that username to login.
