Trouble with Minion Pro Regular

I have trouble with Minion Pro Regular. I've been on vacation for a week and on my return I have problems with this font.

Now I have trouble in Indesign. If I open a document, it wants to activate this font. So Indesign does not work properly.

I've already changed my default to Arial, but if I open an older document, it goes back to Minion. So this didn't fix the problem.

The other thing i've done is to remove the font in Creative Cloud and reinstalled it. But some versions don't want to install. Even If I remove it, Indesign keeps looking for it and it reappears in Creative Cloud if I open an older document.

Can somebody help me?
