Games missing from my EA App library

Okay, I know this is not Sims related, but I honestly don't know where else to put it and I hope that someone can help me with this.
I apologize for putting this in this section, if I knew where to put it other than in here I would have. 

I opened my EA app and went to install a game that I have had in my library since long before EA gameplay was a thing back when we used Origin. I had games that were given away for free. They were Zuma's revenge and Theme Hospital. There was one more, but I forgot the name of it.
I don't really care about Zuma's revenge being missing, but I would like to know why Theme Hospital was removed. It was a free game and I had been looking for a copy of it for 10+ years before it appeared on Origin for free. Now when I look it up it say $4.99. Why should I have to pay for a game that I had in my account for years? It was in my library three days ago and now it's not.

I feel like it was stolen from me and that makes me feel uncomfortable. 

Could someone please help me understand why it's suddenly gone and if possible how to get it back into my account? 
Is this an error that's occurring with the app?

Has this happened to anyone else who had the old free to play games?

Please help.
Thank you.
