LogIn Failing - Can't Open Premiere Pro

Every time I try to open Premiere, I get asked to log in again. When I do that, sometimes I get a message saying premiere failed and other times it opens my project but just asks if I want to save before I close it so I can't do any work! Even if I keep logging in I keep getting the same message -- clearly my login works because I used it to log into this community. 

Any advice??? 

Thank you!!!
