Retrieval of Former Cloud Documents

When I was a student in my masters in 2013-2014 I used to sign in to Adobe through an ID on my Adobe Reader and once I had signed in I uploaded documents to a cloud.  I recently came back to my student account as I'm in a PhD and when I went to sign in the same way it brought me to a new login and to a different site that no longer has those documents and only has things I have recently put in there. 

I'm a little out of touch with the developments here and was wondering if this is the same application (the "assets" thing seems new to me), and if there is a way I could retrieve the documents I had had back when it was just an Adobe ID login through Acrobat. 

P.S. I have checked both the "document cloud" and "creative cloud" in both the personal and enterprise accounts that are linked to the only email account I've ever used with Adobe.
