Licence Problem

Hi everyone ! We are french student at university of Nantes and we are supposed to make an experiment for a research project. We signed-in on pavlovia with our student mail address, but we don’t have the licence we should have, wich should allow us to run our experiment. We first thought it was due to data center’s fire, but since pavlovia is fully back online we should normally have the licence isn’t it ? Is it a know a problem, or do someone gave a solution ? (sorry for my english)
Thank you, have a nice day !
