I have a Creative Cloud account and stupidly hit the upgrade button and started a "trial period" of Photoshop that I already possess. Well, the "trial period" ran out and I no longer have a version of Photoshop to use even though I'm still current. How do I get back to my "old"version of Photoshop?
