Access token is expired

After installing Lightroom CC 1.0 every once in a while I would get an error 67 and would require me to sign out and sign in again.  This would happen every few days or so.  Now, since upgrading to LR CC 1.1 the error 67 has gone away but is now replaced with the following error "Your access token is expired" Please sign out and sign in again.  Signing out and signing in again does not work.  It's only after I reboot that it will fix the issue, albeit temporarily. 

Is anyone else having this issue?  It's a bit frustrating.  Any thoughts?  Is there any sort of log that is captured so I can see why it's erroring out?
