Log out of the creative cloud app, quit it, then launch Photoshop and it'll prompt you to log in.
If that doesn't solve it, then we'll have to get someone from the activation group to provide more instructions.
Just tried those instructions Chris and it still comes up with the same thing that my trial has ended. I can get into Photoshop CS6 as a stand alone. However Lightroom just prompts me to get into CC and of course that turns out as a dead end. On top of all that when I try to liscence the software I get a message that I am not on connected to the internet. Really wierd stuff going on. What is the best way to get a hold of someone from the activation group?
Try opening CC desktop and login there...may help....then start Ps
I'd do above after a computer shutdown and cold restart. And verify you do have an internet connection before starting CC desktop or Ps....like try internet browser to verify it works.
