Problem accessing the course

I registered my kit and when i go to the "chapters" tab suddenly create.arduino.cc says i'm not logged in and display an error message not even giving me an option to log in. When i go back to dashboard i'm logged. So weird and frustrating.

Any ideas ?

Problem was from the arduino create site and is now solved. It was quite quickly solved but i have to say i don't really like the fact the course is hidden from people that did not bought the kit, it's not really int the "arduino" or "maker" or "open source" spirit.
