My free trial of Photoshop CC expired around a week ago, and tonight I bought the Creative Cloud Photography plan (1 year prepaid). However, when I go to open up Photoshop it still just opens up Adobe Application Manager and tells me my trial has expired and gives me the option to either "Join Now" or "License This Software". I tried restarting with no luck, looked under Apps>Desktop on my account and clicked download for Photoshop and followed that through only to have it tell me again that my trial has ended. Am I missing something? Was I supposed to receive a serial number with my purchase or something to license it with or what?
Try opening your Cloud desktop app, signing out then signing in again.
