I have full Creative Cloud. Photoshop CC 2015 disappeared from my system. I tried downloading again but Adobe gave me a trial version. When trial ran out it wanted me to pay ..... but I'm already paying for FULL CC. Tried uninstalling, logging out of CC, logging in, check for updates, download Photoshop ......... but again it says trial expired! Help. Why can't Adobe provide the product I am already paying for?
