Trial period ended

Hello, two week ago I installed the newest version of the Connection Client as well as the LEGION software, and the moment I opened the software I received a warning saying my trial period would end in a week. The period is over now and I can't work anymore, I've tried asking the software manager in my university but they do not know why it isn't working. I would like to know how to get a working license again.

Thank you in advance.
