Stock asking me to log in when I am already logged in!

My account is up to date and all my ususal apps are working fine, but when I launch Stock it is though I do not have an account. I can search for assets but not download them. It prompts me to log in but never launches the log in box. I cannot access mock up psdt files I have already saved to my CC either. 

I have logged out and restarted multiple times. Any help would be great!
