Creative cloud files retrieval on a deactivated school gmail account

Hope everyone is ok, 

I had many important Photoshop files saved on Creative Cloud but after I had finished high school my Gmail was deactivated and now I cannot access Creative Cloud on that account because it was deactivated after I left so I cannot sign in with that account anymore.

I would appreciate any help on this because the files could be very helpful for my portfolio and CV

Thank You
