Why is my Adobe Reader opening and then closing now?

A few days ago my Reader DC suddenly started closing about 8 seconds after I open it.  I have opened and accepted the EULA.  I have uninstalled and reinstalled.  SAme thing happening.  So then I agreed again to the EULA.  Still same thing happening.  I NEED this program!  Please help.  And dumb it down for me please....as I'm not too computer savy.

Thanks!
