Hi,

I am sorry to write about that, but I mad running adobe. Till several days ago Adobe Acrobat Reader DC was working properly, I don't know why, Adobe Reader is not working.

I have my PDF document and when I do doble clic and the program start to run. The icon of Adobe came to my desktop but the document is not appearing on my screen. My OS is High Sierra 10.13.6. 

I already have installed Adobe again, I spoke with Mac customer service and can open Pdf with another application, so, What is happening?

Help please.

Thank you to read me.
