Sudden Restriction of AE Access

I have been using Adobe Express for a year or two now at this point. I am in charge of the social media of two social groups at my higher educations institution and I use Adobe Express to get my work done almost every single day. I have a lot of projects to be working on right now and so it is much to my despair that everytime I open the site/app I am welcomed with an error message stating "You do not have access to Adobe Express." I used my school's email with the understanding that I would have some sort of enterprise account access to Adobe Express and it has never been a problem until recently. Is Adobe Express not free to use? Why would I suddenly lose access to the program? It says to gain access I need to submit a request to my IT administrator but I do not even know where to begin to know who that is. Has anyone else had this issue?
