Access to the Files in Cloud

Last year, I got a subscription to Creative Cloud, covering all the Adobe products, via my institution, and I was using the Cloud to save my documents in Illustrator and Photoshop. At the end of November, my subscription is renewed (the same email and again through my institution). However, right now, I cannot access my files in the cloud because it says I'm not the owner. It also says that I can use Illustrator only with the files on my local computer. I don't know how I can access my files and solve this issue.
