Acrobat Reader don't open some PDF file

[jacopos37819286]

Good morning, everyone,

I'd need your help. I have a problem with Acrobat Reader DC which can't open the compilable files and sign them.
I think it is a problem of user preferences as it is the only one that has problems.

On windows where can I find the preferences of the program about that user and then delete them?
How do I do it?

Or do you have other suggestions to give me?

I add that the program opens but then freezes and indicates 'not responding'.

Jacopo.
