Lightroom Shared Album is "Unavailable"

Hi everybody! 

I have a question about my Lightroom shared albums. 

When I was in college, I had access to Adobe for free, and I used my college email account to create many albums. Before I graduated, I shared each of the albums with my personal account so that I could still have access to them. They worked initially! However, now when I try to open any of them, I get this message: 

“This shared album is currently unavailable. Please contact the album owner for more information.” 

I know that my college account is the “owner”, but I can’t log into adobe using the college account anymore. How can I restore (?) or find these photos? We are talking 20+ albums with hundreds of photos each.

I tried calling adobe support and they hung up on me twice after I had completed all the “press x for y” options.

Any tips? Answers? Are they gone forever?  I still have all the raws from most of those shoots but I didn’t download all the edited photos- I mostly shared them with others for them to download.
